Growth is an increase in physical size. Track it with weight, length or height, and head circumference when appropriate. Development is the progressive attainment of skills — what the child can do.
Two directional rules govern motor development. Gross motor skills — the big movements like rolling, sitting, and walking — develop head to toe. Fine motor skills — the small, precise movements like grasping and drawing — progress center to periphery, from the trunk outward to the fingers.
Two theorists organize the whole lecture. Erikson describes the emotional task of each stage; Piaget describes how thinking works at each stage.
Growth is explosive: weight doubles by 4–5 months and triples by 12 months. Milestones stack in order. Gross motor: roll, then sit, then crawl, then stand. Fine motor: transfer objects hand to hand, then pincer grasp — picking things up between thumb and finger. Language: coo, then babble, then first meaningful words.
The nursing focus is the Erikson task: respond consistently and keep caregivers involved, because consistent responses build trust. Safety teaching centers on back to sleep, a safe crib, choking prevention, and car-seat safety. Stranger anxiety and separation anxiety emerging later in infancy are normal — they actually signal healthy attachment.
Growth slows to about 3–5 pounds and 3 inches per year. Mobility explodes: walk, then run, then climb. Fine motor: use a spoon, scribble, stack blocks. Language: combining two words around age 2.
Honor the autonomy task in your nursing care: offer two realistic choices ("red shirt or blue shirt?") and keep directions simple. Socially, expect parallel play — the toddler plays beside other children, not with them — and that's normal, not a delay. Appetite often drops and food jags appear (the child eats only one food for days); both are common. The safety list is the toddler's danger list: poisoning, drowning, burns, and falls.
Growth runs about 4–5 pounds and 2.5–3 inches per year. Gross motor: hop, then balance, then skip. Fine motor: draw shapes, use scissors, dress self. Language blossoms into telling stories.
Nursing care runs on two tools: explain procedures in concrete words and use play (a pretend clinic with a toy kit is perfect). Understand magical thinking — the preschooler believes thoughts and wishes cause real events, so a child may believe illness is punishment for being bad. Name that fear, correct it gently, recognize other fears, and invite the child to participate in care.
Growth is steady: about 2–2.5 inches and 4–7 pounds each year. Coordination, writing, and reading improve, and organized activities take hold. These children think in concrete operations — they're logical, but about real, tangible things — so teach with real examples.
Nursing approach: explain what will happen and why, and give the child a useful role in their own care. What matters most to them now: school success, peer relationships, body image, and bullying — ask about all four.
Puberty brings rapid growth, and timing varies widely — reassure teens that variation is normal. Thinking goes formal operational: abstract, hypothetical, "what if" reasoning. Peers become central to identity and support.
Nursing care shifts accordingly: speak directly to the adolescent (not over them to the parent), be respectful, protect privacy, and explain the limits of confidentiality honestly. Invite them into decisions about their care, and routinely assess body image, mood, sexual health, substance use, and injury risks.
Play is the social-development vital sign. Infants do solitary sensory play — rattles, caregiver interaction. Toddlers do parallel play — blocks, shape sorters, push toys, alongside others. Preschoolers move into associative and imaginative play — pretend play, simple art, starting to interact. School-age children do cooperative, rule-based activities — games with rules, crafts, team activities. Adolescents center on peers — social connection and independent interests.
For infants and toddlers: keep the caregiver close, comfort the infant, and give the toddler brief directions with limited choices. For preschool and school-age children: use concrete explanations and therapeutic play; tell the school-age child what will happen and assign a useful role. For adolescents: speak to them directly, offer privacy and participation, and allow appropriate peer contact during hospitalization.
Infants: breastmilk or formula first; introduce complementary foods when the infant shows readiness, around 6 months. Toddlers and preschoolers: appetite naturally slows as growth slows — offer child-sized portions, use repeated exposure to new foods, and never force food. School-age children and adolescents: assess usual intake, food access, and activity level; support healthy choices while acknowledging peer influence and growing independence.
Infant/toddler: no meaningful words by 12 months, loss of a previously attained skill (regression), or delayed language/motor progress compared with adjusted age. Preschool/school age: no interest in playing with other children, or difficulty functioning at school — explore hearing, vision, social, and learning concerns. Adolescent: marked behavior change, isolation, bullying, or suicidal thoughts — assess safety promptly and connect to support.
