Growth and Developmental Theories
Comprehensive Nursing Notes on Major Developmental Theorists
Introduction to Developmental Theories
Developmental theories provide frameworks for understanding how humans grow and change throughout their lifespan. These theories help nurses assess, plan, and implement care appropriate to a patient’s developmental stage. Each theory focuses on different aspects of development:
Freud’s Psychosexual Theory
Focuses on how the sexual energy (libido) drives development through various erogenous zones of the body.
Erikson’s Psychosocial Theory
Emphasizes social relationships and how individuals navigate psychological crises at each life stage.
Piaget’s Cognitive Theory
Describes how children’s thinking and understanding of the world develop through distinct stages.
Kohlberg’s Moral Theory
Explains how moral reasoning develops from self-interest to principles of universal ethical values.
Freud’s Psychosexual Development Theory
Understanding development through the lens of sexual energy (libido)
Overview
Sigmund Freud (1856-1939) proposed that personality development occurs through a series of childhood stages during which the pleasure-seeking energies of the id become focused on specific erogenous zones. This psychosexual energy, or libido, was described as the driving force behind behavior.
Clinical Relevance for Nurses
Understanding Freud’s theory helps nurses recognize how early childhood experiences may influence adult behaviors and psychological issues. This can inform therapeutic communication and care planning for patients with psychological disorders.
Key Concepts
- Libido: Psychosexual energy that drives behavior
- Fixation: Occurs when developmental needs are not met at a specific stage
- Id, Ego, Superego: Components of personality that develop during psychosexual stages
- Erogenous Zones: Body areas that are particularly sensitive to stimulation
The Five Stages of Psychosexual Development
| Stage | Age | Focus | Description | Potential Fixation |
|---|---|---|---|---|
| Oral | Birth – 1 year | Mouth | Pleasure derived from oral stimulation (sucking, feeding, biting) | Smoking, overeating, nail biting, excessive dependency or pessimism |
| Anal | 1-3 years | Bowel Control | Pleasure from withholding and expelling feces; toilet training conflict | Anal retentive: orderly, rigid, obsessive or Anal expulsive: messy, destructive |
| Phallic | 3-6 years | Genitals | Discovery of genital differences; Oedipus/Electra complex | Sexual inhibition, gender identity issues, vanity |
| Latency | 6-12 years | Sexual dormancy | Sexual urges repressed; focus on skills and same-sex friendships | Difficulty forming relationships, workaholic tendencies |
| Genital | 12+ years | Sexual maturity | Development of mature sexual interests and relationships | Relationship difficulties if previous stages unresolved |
Mnemonic: “Oh All People Love Growth”
- Oral Stage (0-1 years)
- Anal Stage (1-3 years)
- Phallic Stage (3-6 years)
- Latency Stage (6-12 years)
- Genital Stage (12+ years)
Erikson’s Psychosocial Development Theory
Understanding development through social relationships and psychological crises
Overview
Erik Erikson (1902-1994) expanded on Freud’s theory to include the entire lifespan and emphasized social and cultural influences on development. He proposed that individuals face psychosocial crises at each stage that must be resolved to develop a healthy personality and acquire basic virtues.
Clinical Relevance for Nurses
Erikson’s theory provides a framework for understanding patients’ developmental needs across the lifespan. Nurses can use this knowledge to create age-appropriate interventions, support healthy crisis resolution, and identify when patients may be struggling with unresolved developmental issues.
Key Concepts
- Psychosocial Crisis: Developmental conflict that needs resolution
- Basic Virtues: Psychological strengths gained from successful resolution
- Epigenetic Principle: Development unfolds according to a predetermined sequence
- Lifespan Approach: Development continues throughout life, not just childhood
The Eight Stages of Psychosocial Development
| Stage | Age | Psychosocial Crisis | Basic Virtue | Description | Nursing Implications |
|---|---|---|---|---|---|
| 1 | 0-18 months | Trust vs. Mistrust | Hope | Infants learn to trust that their needs will be met by caregivers | Promote consistent, responsive caregiving; support parent-infant bonding |
| 2 | 18 mo – 3 yrs | Autonomy vs. Shame & Doubt | Will | Toddlers develop independence and self-control | Encourage safe exploration; provide choices; avoid shame in toilet training |
| 3 | 3-5 years | Initiative vs. Guilt | Purpose | Preschoolers initiate activities and develop conscience | Support creativity; allow appropriate risk-taking; avoid excessive criticism |
| 4 | 5-12 years | Industry vs. Inferiority | Competence | School-age children develop skills and sense of accomplishment | Praise effort; promote problem-solving; support learning activities |
| 5 | 12-18 years | Identity vs. Role Confusion | Fidelity | Adolescents develop a coherent sense of self | Respect privacy; provide opportunities for self-expression; avoid labeling |
| 6 | 18-40 years | Intimacy vs. Isolation | Love | Young adults form close, committed relationships | Support healthy relationships; address isolation in care settings |
| 7 | 40-65 years | Generativity vs. Stagnation | Care | Middle-aged adults contribute to society and future generations | Recognize accomplishments; encourage mentoring; support work-life balance |
| 8 | 65+ years | Integrity vs. Despair | Wisdom | Older adults reflect on life with satisfaction or regret | Provide life review opportunities; respect autonomy; support dignity |

Piaget’s Cognitive Development Theory
Understanding how children think and construct knowledge of the world
Overview
Jean Piaget (1896-1980) focused on how children’s thinking develops through distinct stages. He proposed that children are active learners who construct knowledge through their experiences with the environment. Piaget believed that cognitive development follows a fixed sequence of stages, with each stage building upon the previous one.
Clinical Relevance for Nurses
Understanding Piaget’s theory helps nurses tailor education and communication to a child’s cognitive abilities. This knowledge informs how to explain medical procedures, prepare children for hospitalization, and develop age-appropriate teaching materials for pediatric patients and their families.
Key Concepts
- Schema: Mental frameworks or concepts used to organize and interpret information
- Assimilation: Incorporating new information into existing schemas
- Accommodation: Modifying existing schemas to fit new information
- Equilibration: Balancing assimilation and accommodation to achieve cognitive stability
The Four Stages of Cognitive Development
| Stage | Age | Key Characteristics | Important Milestones | Nursing Implications |
|---|---|---|---|---|
| Sensorimotor | Birth – 2 years | Learning through senses and motor activities; developing object permanence |
|
Use sensory stimulation; maintain consistency; provide object permanence games |
| Preoperational | 2-7 years | Symbolic thinking; egocentrism; intuitive rather than logical reasoning |
|
Use concrete explanations; provide drawing opportunities; be aware of magical thinking about illness |
| Concrete Operational | 7-11 years | Logical thinking about concrete events; understanding of conservation; classification |
|
Use visual aids; provide hands-on demonstrations; explain cause-effect relationships |
| Formal Operational | 11+ years | Abstract reasoning; hypothetical thinking; scientific reasoning; idealism |
|
Involve in decision-making; discuss long-term consequences; address hypothetical concerns |
Mnemonic: “Some People Can Fly”
- Sensorimotor Stage (Birth-2 years)
- Preoperational Stage (2-7 years)
- Concrete Operational Stage (7-11 years)
- Formal Operational Stage (11+ years)
Conservation Tasks Development
Conservation is the understanding that quantity remains the same despite changes in appearance. Children in the concrete operational stage begin to master different types of conservation:
Number (Age 6-7)
Understanding that spreading out items doesn’t change their quantity
Length (Age 6-7)
Understanding that changing the position of objects doesn’t alter their length
Liquid (Age 7-8)
Understanding that liquid amount stays the same when poured into different containers
Mass (Age 7-8)
Understanding that clay or playdough amount remains same when shape changes
Weight (Age 9-10)
Understanding that an object’s weight is conserved despite shape changes
Volume (Age 10-12)
Understanding that displacement of water by an object isn’t affected by the object’s shape
Kohlberg’s Moral Development Theory
Understanding how moral reasoning evolves through distinct stages
Overview
Lawrence Kohlberg (1927-1987) extended Piaget’s work to examine how moral reasoning develops. Based on responses to moral dilemmas, Kohlberg identified three levels of moral development, each containing two stages. His theory focuses on the reasoning process behind moral decisions rather than the decisions themselves.
Clinical Relevance for Nurses
Understanding Kohlberg’s theory helps nurses assess patients’ decision-making processes, especially in ethical situations. It guides nurses in communicating about treatment decisions, advance directives, and end-of-life care in ways that align with a patient’s moral reasoning level.
Key Concepts
- Moral Reasoning: The cognitive process used to judge right from wrong
- Moral Dilemmas: Situations with conflicting moral principles
- Justice Orientation: Focus on fairness and rights
- Sequential Development: Stages unfold in a fixed order
The Three Levels and Six Stages of Moral Development
Focus on self-interest and consequences
“I don’t want to get in trouble”
“What’s in it for me?”
Focus on social rules and expectations
“I want to please others”
“We must follow society’s rules”
Focus on abstract principles and values
“Laws are agreements that can change”
“There are universal ethical principles”
| Level | Stage | Age | Description | Motivation | Nursing Implications |
|---|---|---|---|---|---|
| Preconventional | Stage 1: Punishment-Obedience |
~2-7 years | Actions judged by consequences; rules followed to avoid punishment | Avoidance of punishment | Explain consequences clearly; focus on immediate outcomes |
| Stage 2: Instrumental Relativist |
~7-10 years | Actions judged by how they serve one’s needs; follows rules for rewards or exchanges | Self-interest, “What’s in it for me?” | Use reward systems; emphasize personal benefits of health behaviors | |
| Conventional | Stage 3: Interpersonal Concordance |
~10-13 years Adolescence |
Actions judged by social approval; desires to be “good” in others’ eyes | Maintaining relationships, being liked | Appeal to peer norms; highlight social approval of healthy behaviors |
| Stage 4: Law and Order |
Adolescence Adulthood |
Actions judged by societal rules; emphasis on duty and respect for authority | Maintaining social order | Appeal to rules and duties; reference healthcare standards | |
| Postconventional | Stage 5: Social Contract |
Adulthood (Some never reach) |
Recognition that rules are social agreements that can be changed; focus on rights and welfare | Social contract, greater good | Discuss ethical implications; acknowledge patient values in care decisions |
| Stage 6: Universal Ethical Principles |
Adulthood (Few reach) |
Actions guided by abstract, universal ethical principles of justice and human rights | Universal ethical principles | Engage in ethical discussions; support autonomous decision-making |
Mnemonic: “Please Include Learning Social Understanding”
- Punishment Avoidance (Stage 1)
- Instrumental Exchange (Stage 2)
- Liking/Approval (Stage 3)
- Social Order (Stage 4)
- Universal Rights (Stages 5 & 6)
Heinz Dilemma
Kohlberg used moral dilemmas to assess moral reasoning. The most famous is the Heinz Dilemma:
A woman is dying from a special kind of cancer. There is one drug that might save her, discovered by a pharmacist who is charging ten times what it costs to make. The sick woman’s husband, Heinz, can only raise half the money. He asks the pharmacist to sell it cheaper or let him pay later, but the pharmacist refuses. Should Heinz steal the drug to save his wife?
Sample responses by stage:
- Stage 1: “Heinz shouldn’t steal because he might get caught and go to jail.”
- Stage 2: “Heinz should steal it because he needs his wife to take care of him.”
- Stage 3: “Heinz should steal it because his wife expects him to care for her.”
- Stage 4: “Stealing is illegal, so Heinz shouldn’t do it.”
- Stage 5: “Heinz should steal it because the right to life takes precedence over property rights.”
- Stage 6: “Heinz should act on the principle that preserving human life is more important than following laws that protect property.”
Comparison of Developmental Theories
Understanding how these theories complement and differ from each other helps nurses develop a more holistic view of human development.
| Feature | Freud | Erikson | Piaget | Kohlberg |
|---|---|---|---|---|
| Focus | Psychosexual development | Psychosocial development | Cognitive development | Moral reasoning development |
| Primary Driver | Sexual energy (libido) | Social relationships | Active construction of knowledge | Understanding of justice/fairness |
| Period Covered | Childhood to young adulthood | Entire lifespan | Childhood to adolescence | Early childhood to adulthood |
| Number of Stages | 5 stages | 8 stages | 4 stages | 6 stages (3 levels) |
| Role of Environment | Medium emphasis | Strong emphasis | Strong emphasis | Medium emphasis |
| Research Methods | Clinical case studies | Observations, case studies | Observations, interviews | Responses to moral dilemmas |
| Primary Limitations | Limited empirical support; overemphasis on sexuality | Vaguely defined stages; cultural limitations | Underestimated children’s abilities; cultural limitations | Gender bias; cultural limitations; focus on justice over care |

Introduction to Child Development
Child development is a dynamic and continuous process that involves physical, cognitive, social, and emotional growth. Understanding the typical developmental milestones and children’s needs at each stage helps parents and healthcare providers support healthy development and identify potential concerns early.
Key Concept:
While development follows predictable patterns, each child develops at their own pace. The age ranges provided are approximate guidelines rather than strict rules.
Four Domains of Development
Physical
Growth, motor skills, physical capabilities, and sensory development
Cognitive
Thinking, learning, problem-solving, memory, and language development
Social
Relationships, interaction with others, communication, and play skills
Emotional
Understanding and expressing feelings, self-awareness, and self-regulation
Mnemonic for Developmental Domains: “PCSE”
- Physical: How they grow and move
- Cognitive: How they think and learn
- Social: How they interact with others
- Emotional: How they feel and regulate emotions
Infancy (Birth to 1 Year)
Physical Development
0-3 months
- Raises head and chest when lying on stomach
- Stretches and kicks when lying on back
- Opens and closes hands
- Brings hands to mouth
4-6 months
- Rolls over in both directions
- Sits with and eventually without support
- Supports weight on legs; might bounce
- Reaches for objects with both hands
7-9 months
- Begins crawling
- Pulls to stand
- Sits without support
- Develops pincer grasp (thumb and forefinger)
10-12 months
- Cruises furniture; may take first steps
- Stands alone briefly
- Grasps small objects with precision
- May start feeding self with fingers
Physical Development Red Flags:
- Not reaching for objects by 4 months
- Not rolling over in either direction by 6 months
- Unable to sit with support by 8 months
- Not crawling by 12 months
Cognitive Development
Infants learn about the world through their senses and actions, developing what Piaget called sensorimotor intelligence.
| Age | Cognitive Milestones |
|---|---|
| 0-3 months |
|
| 4-6 months |
|
| 7-9 months |
|
| 10-12 months |
|
Key Concept: Object Permanence
The understanding that objects continue to exist even when they cannot be seen, heard, or touched. This typically develops around 8 months and is a critical cognitive milestone.
Social & Emotional Development
Emotional Development
- Forms secure attachment to caregivers
- Expresses various emotions (joy, fear, anger)
- Self-soothes (e.g., sucking thumb)
- Develops separation anxiety (8-12 months)
- Shows emotional responses to others’ emotions
Important Concept: Attachment
The emotional bond between infant and caregiver is crucial for healthy development. Secure attachment provides a foundation for future relationships and emotional regulation.
Social/Emotional Red Flags:
- Rarely makes eye contact or smiles by 3 months
- Doesn’t respond to sounds or voices
- Shows little interest in people by 8 months
- Seems unresponsive to comfort when distressed
Parental Guidance for Infancy
Mnemonic: “LOVES”
- Love and nurture consistently
- Observe and respond to cues
- Vocalize and communicate often
- Engage through play and exploration
- Safety-proof environment
Essential Parental Guidance:
Physical Needs Support
- Provide regular tummy time when awake
- Create safe spaces for movement and exploration
- Ensure proper nutrition (breastfeeding/formula)
- Establish consistent sleep routines
- Attend all well-baby checkups
Cognitive Development Support
- Talk, read, and sing to your baby daily
- Describe what you’re doing during routines
- Provide age-appropriate toys with different textures, sounds, and colors
- Play simple games like peek-a-boo
Social/Emotional Support
- Respond promptly to cries and distress
- Hold, cuddle, and comfort regularly
- Make eye contact and smile during interactions
- Recognize and respect temperament differences
- Create predictable routines for security
Communication Support
- Respond to baby’s coos and babbles
- Use “parentese” (higher pitch, slower speech)
- Name objects and people in the environment
- Use simple gestures with words
Nursing Tip:
Educate parents that responsive caregiving—promptly and appropriately responding to an infant’s needs—builds trust and security, not “spoiling.” It helps develop healthy brain connections and emotional regulation skills.
Toddlerhood (1-3 Years)
Physical Development
12-18 months
- Walks independently
- Begins to run (often awkwardly)
- Climbs on furniture
- Stacks 2-4 blocks
- Feeds self with fingers and begins using utensils
18-24 months
- Runs with increasing skill
- Kicks and throws balls
- Climbs stairs with help
- Scribbles spontaneously
- Removes simple clothing items
24-36 months
- Jumps with both feet
- Walks up and down stairs alternating feet
- Rides tricycle using pedals
- Holds crayon with fingers, not fist
- Turns pages in a book one at a time
- Begins toilet training readiness
Toilet Training Readiness Signs:
- Stays dry for 2+ hours
- Recognizes when diaper is wet/soiled
- Shows interest in toilet or potty chair
- Can follow simple instructions
- Can pull pants up and down
Cognitive Development
Toddlers move from sensorimotor to preoperational stage in Piaget’s theory. They develop symbolic thinking but remain egocentric.
| Age | Cognitive Milestones |
|---|---|
| 12-18 months |
|
| 18-24 months |
|
| 24-36 months |
|
Language Development:
- 12-18 months: 5-20 words, understands more
- 18-24 months: 50-200 words; combines two words
- 24-36 months: 200-1,000 words; uses 3-4 word sentences; asks questions
Social & Emotional Development
Emotional Development
- Develops sense of self-awareness
- Shows pride in accomplishments
- Experiences range of emotions intensely
- May have frequent tantrums (especially 18-24 months)
- Develops early empathy
Autonomy and Independence
According to Erikson, toddlers are in the “Autonomy vs. Shame and Doubt” stage. They need opportunities to make choices and do things for themselves within safe boundaries. This builds confidence and a sense of control.
Social/Emotional Red Flags:
- Limited interest in other children by 2 years
- Extreme or prolonged separation anxiety
- Doesn’t notice or respond to others’ emotions
- Excessive aggression or frequent, severe tantrums
- Limited range of emotional expression
Parental Guidance for Toddlerhood
Mnemonic: “TEACH”
- Tolerante of developmental behaviors
- Establish clear, consistent boundaries
- Allow choices within limits
- Connect during positive moments
- Help navigate big emotions
Essential Parental Guidance:
Supporting Independence
- Offer limited choices (“red cup or blue cup?”)
- Allow extra time for self-help tasks
- Create accessible environments (low hooks, step stools)
- Praise efforts, not just successes
Managing Challenging Behaviors
- Use positive redirection
- Establish consistent routines and rules
- Use simple explanations
- Employ natural consequences when safe
- Use time-in rather than time-out
Supporting Emotional Regulation
- Label emotions (“You feel frustrated”)
- Accept all emotions while limiting behaviors
- Model calm responses to stress
- Offer comfort during distress
- Teach simple calming strategies (deep breaths)
Promoting Language and Learning
- Read books daily with interactive discussion
- Expand on child’s language (“Car go” → “Yes, the car is going fast”)
- Limit screen time; prioritize interaction
- Provide sensory-rich play experiences
Nursing Tip:
Help parents understand that tantrums are normal developmental behaviors, not manipulation. They result from limited language skills, big emotions, and developing self-regulation. Responding with consistent, calm support helps toddlers develop emotional regulation.
Preschool Age (3-5 Years)
Physical Development
3-4 years
- Climbs well
- Runs easily, with improved coordination
- Pedals tricycle
- Walks up and down stairs, alternating feet
- Throws ball overhand

- Hops and skips
- Swings and climbs
- May be able to skip
- Copies shapes and some letters
- Uses scissors to cut on a line
- Dresses and undresses independently
Fine Motor Skills Development:
Fine motor skills develop rapidly during the preschool years. Activities that support this development include:
- Stringing beads
- Using child-safe scissors
- Drawing and coloring
- Playing with playdough
- Pouring and scooping
Cognitive Development
Preschoolers are in Piaget’s preoperational stage. They develop symbolic thinking, but their thinking remains concrete and often egocentric.
| Cognitive Characteristic | Description & Examples |
|---|---|
| Symbolic thinking | Uses symbols to represent objects; engages in pretend play (“This block is my phone”) |
| Egocentrism | Difficulty seeing perspectives other than their own; assumes others see, think, and feel as they do |
| Magical thinking | Believes in magic; may create imaginary explanations for things they don’t understand |
| Animism | Attributes life and feelings to inanimate objects (“My teddy is sad”) |
| Centration | Focuses on one aspect of a situation and ignores others; lacks conservation (doesn’t understand that quantity remains the same despite changes in appearance) |
Language Development:
- Speaks in complete sentences of 4-5 words
- Uses past tense and plurals (sometimes incorrectly)
- Asks many questions, especially “why?”
- Tells stories and recalls parts of stories
- By 5, uses proper grammar most of the time
- Vocabulary of 1,500-2,000 words by age 5
Social & Emotional Development
Emotional Development
- Shows wider range of emotions
- Separates from parents more easily
- Expresses feelings verbally
- Develops more sophisticated self-regulation
- May develop specific fears
- Shows empathy and concern for others
Erikson’s Stage: Initiative vs. Guilt
Preschoolers are eager to take initiative, try new things, and assert themselves. When supported in safe exploration and expression, they develop purpose and confidence. If consistently discouraged or punished for initiative, they may develop guilt about their desires and impulses.
Social/Emotional Red Flags:
- Shows little interest in other children
- Extreme difficulty separating from parents
- Doesn’t engage in pretend play
- Poor eye contact or social reciprocity
- Extreme or persistent aggressive behavior
Parental Guidance for Preschool Age
Mnemonic: “PLAYS”

- Answer questions honestly and simply
- Yield control when appropriate
- Support learning through play
Essential Parental Guidance:
Supporting Cognitive Development
- Encourage pretend play and creativity
- Ask open-ended questions
- Provide materials for exploration
- Read interactively; discuss stories
- Visit museums, parks, libraries
Promoting Social Skills
- Arrange playdates with peers
- Teach and model sharing and turn-taking
- Help navigate conflicts (without solving all problems)
- Acknowledge kind behaviors
- Discuss others’ feelings and perspectives
Emotional Development Support
- Label and validate emotions
- Teach appropriate emotional expression
- Help identify coping strategies
- Maintain consistent boundaries
- Use natural consequences for teaching
School Readiness
- Establish predictable routines
- Encourage self-help skills
- Develop listening and following directions
- Practice sitting still for short periods
- Support early literacy skills (letter recognition, phonological awareness)
Nursing Tip:
Educate parents about addressing preschoolers’ “Why?” questions. They should answer honestly but simply, at the child’s level of understanding. This nurtures curiosity and builds language skills. If parents don’t know an answer, they can say “I’m not sure. Let’s find out together,” modeling lifelong learning.
School Age (6-12 Years)
Physical Development
Early School Age (6-8 years)
- Improved coordination and balance
- Rides bicycle without training wheels
- Ties shoelaces
- Improved fine motor control for writing
- Loses first teeth; permanent teeth begin appearing
- Grows about 2-3 inches per year
Middle/Late School Age (9-12 years)
- Increased strength and endurance
- Improved sports skills
- Greater manual dexterity
- Girls may begin puberty (breast development, height spurt)
- Growth rate varies widely among peers
- Improved handwriting and drawing abilities
Puberty Timeline:
Girls typically begin puberty between ages 8-13, while boys typically begin between ages 9-14. Early signs include:
- Girls: Breast development, growth spurt, pubic hair
- Boys: Testicular enlargement, growth spurt, pubic hair
Physical Development Support:
School-age children need 60 minutes of physical activity daily, including:
- Aerobic activity (running, swimming)
- Muscle-strengthening activities (climbing, gymnastics)
- Bone-strengthening activities (jumping, sports)
Cognitive Development
School-age children enter Piaget’s concrete operational stage. They develop logical thinking about concrete events but still struggle with abstract concepts.
| Cognitive Skill | Description |
|---|---|
| Conservation | Understands that quantity remains the same despite changes in appearance (e.g., same amount of water in different shaped containers) |
| Classification | Can sort objects by multiple characteristics (e.g., by color and shape) |
| Reversibility | Understands that actions can be reversed (e.g., 3+4=7 and 7-4=3) |
| Decentration | Can focus on multiple aspects of a problem simultaneously |
| Serialization | Can arrange objects in logical order (e.g., by size or weight) |
Academic Development:
- 6-7 years: Begins reading and basic math
- 8-9 years: Reads with comprehension; writes stories; multiplication/division
- 10-12 years: Researches topics; critical thinking; complex math concepts
Learning Challenges to Watch For:
- Difficulty with reading (dyslexia)
- Problems with writing (dysgraphia)
- Math challenges (dyscalculia)
- Attention difficulties (ADHD)
- Memory or processing issues
Social & Emotional Development
Emotional Development
- Develops more stable self-concept
- Shows increased emotional regulation
- Forms more realistic self-evaluation
- Compares self to peers
- Develops sense of competence and accomplishment
- May experience mood swings as puberty approaches
Erikson’s Stage: Industry vs. Inferiority
School-age children are focused on developing competence and mastery. Success in academics, sports, arts, and other areas helps them develop a sense of industry (competence and productivity). Consistent failure or criticism can lead to feelings of inferiority that may persist into adulthood.
Important:
Bullying often peaks during late elementary school years. Children need guidance in identifying, reporting, and responding to bullying behavior, whether they are targets, bystanders, or engaging in bullying themselves.

School-age children are increasingly aware of their performance compared to peers. Help parents understand the importance of identifying each child’s unique strengths and providing opportunities for success. This builds self-esteem and resilience that carry into adolescence and adulthood.
Adolescence (13-18 Years)
Physical Development
Female Development
- Breast development continues
- Menstruation begins (typically 12-14 years)
- Height spurt (peak around 11.5-12.5 years)
- Widening of hips; increased body fat
- Public, underarm, and body hair development
- Skin and sweat gland changes; possible acne
Male Development
- Testicular and penile enlargement
- Height spurt (peak around 13.5-14.5 years)
- Voice deepening
- Muscle development and broadening shoulders
- Public, facial, underarm, and body hair development
- Skin and sweat gland changes; possible acne
Important Health Considerations:
- Sleep needs increase (8-10 hours recommended)
- Nutritional needs increase during growth spurts
- Brain development continues through adolescence and into early 20s
- Physical development may not align with emotional/cognitive maturity
- Significant variability in timing and rate of development among peers
Health Risk Behaviors:
Adolescents may engage in risk behaviors as part of identity development and due to incomplete brain development (especially prefrontal cortex). Watch for:
- Substance use/experimentation
- Risky sexual behavior
- Dangerous driving
- Disordered eating patterns
Cognitive Development
Adolescents enter Piaget’s formal operational stage. They develop abstract thinking, hypothetical reasoning, and metacognition.
| Cognitive Ability | Description |
|---|---|
| Abstract thinking | Can think about concepts not tied to concrete examples; understands metaphors, symbolism |
| Hypothetical reasoning | Can think about possibilities and hypothetical situations; considers “what if” scenarios |
| Deductive reasoning | Can draw logical conclusions from general principles |
| Metacognition | Thinks about their own thinking processes; can evaluate their thought patterns |
| Future planning | Begins considering long-term goals and consequences; thinks about the future |
Adolescent Cognitive Characteristics:
- Idealism: Envisions perfect solutions and becomes critical of actual conditions
- Argumentativeness: Tests reasoning abilities through debate and discussion
- Self-consciousness: Heightened awareness of own thoughts and belief that others are equally focused on them (“imaginary audience”)
- Invulnerability: Belief that negative consequences won’t affect them (“personal fable”)
Social & Emotional Development
Emotional Development
- Experiences intense and fluctuating emotions
- Develops more defined sense of identity
- Questions established norms and values
- Increasing capacity for empathy and perspective-taking
- Improved emotional regulation (gradually)
- Develops greater self-awareness
Erikson’s Stage: Identity vs. Role Confusion
Adolescents are focused on developing a coherent sense of self and personal identity. This involves exploring values, beliefs, interests, and roles. Successful resolution leads to a strong sense of identity; difficulties in this stage can lead to role confusion and uncertainty about one’s place in the world.
Mental Health Awareness:
Adolescence is a peak period for the onset of mental health conditions. Watch for:
- Significant mood changes or persistent sadness
- Withdrawal from previously enjoyed activities
- Changes in sleep, appetite, or energy
- Excessive worrying or anxiety
- Self-harming behaviors
- Suicidal thoughts or expressions
Parental Guidance for Adolescence
Mnemonic: “ADAPT”
- Allow appropriate autonomy
- Discuss values and difficult topics
- Appreciate their unique identity
- Provide consistent boundaries
- Trust and respect their growing capabilities
Essential Parental Guidance:
Supporting Independence
- Gradually increase privileges with responsibility
- Allow appropriate decision-making
- Respect privacy while maintaining supervision
- Involve teens in creating reasonable rules
- Focus on guidance rather than control
Communication Strategies
- Listen without judgment or immediate solutions
- Respect their perspective even when disagreeing
- Choose battles carefully
- Have important conversations during calm times
- Use open-ended questions to promote dialogue
Health and Safety Guidance
- Discuss sensitive topics openly and honestly
- Provide accurate information about sexuality
- Address substance use with facts, not just warnings
- Promote healthy risk-taking alternatives
- Model healthy coping strategies
Identity Development Support
- Encourage exploration of interests and talents
- Respect evolving values and beliefs
- Support positive self-concept
- Discuss future goals without imposing expectations
- Affirm their worth beyond achievements
Nursing Tip:
Adolescents often test boundaries as part of developing identity and autonomy. Advise parents to maintain consistent boundaries while providing increasing freedom in appropriate areas. The most effective parenting style combines warmth and support with clear expectations and reasonable limits.

Conclusion: Supporting the Whole Child
Understanding the needs of children at different developmental stages allows parents, caregivers, and healthcare providers to offer appropriate support that nurtures healthy development. While each stage presents unique challenges and opportunities, several principles remain constant throughout childhood:
Individualized Approach
Each child is unique with their own temperament, strengths, challenges, and developmental timeline. While developmental milestones provide important guidelines, the focus should be on supporting each child’s individual path rather than strict comparisons to norms or peers.
Relationship-Based Care
Secure, responsive relationships provide the foundation for all aspects of development. Children thrive when they have consistent, caring relationships with adults who are attuned to their needs, responsive to their communication, and supportive of their growing autonomy.
Holistic Development
Physical, cognitive, social, and emotional domains of development are interconnected. Supporting the whole child means attending to all developmental domains and understanding how they influence each other throughout childhood.
Evolving Guidance
Effective parental guidance evolves as children develop. What works for a toddler is not appropriate for an adolescent. The balance of nurture and structure, support and challenge, protection and autonomy must be continuously adjusted to meet changing developmental needs.
Key Nursing Role in Supporting Development
Nurses play a vital role in supporting child development through:
- Conducting developmental screenings and assessments
- Providing anticipatory guidance to parents about upcoming developmental stages
- Educating about age-appropriate activities and safety measures
- Identifying developmental concerns early and facilitating referrals
- Supporting families during transitions between developmental stages
- Promoting positive parenting practices that support healthy development
By understanding the normal developmental needs of children and providing appropriate guidance to parents, nurses contribute significantly to the healthy development of children, helping them reach their full potential across all domains of development.
