Chapter 7: Health Promotion During Early Childhood

The physiological foundation begins with understanding that growth decelerates after infancy, manifesting in reduced appetite and selective eating patterns that parents often misinterpret as problematic. Body composition gradually shifts from a characteristic pot-bellied appearance toward more proportionate limbs and trunk. Motor skill acquisition proceeds sequentially, with gross motor abilities like ambulation, running, and climbing developing alongside fine motor coordination necessary for drawing, self-feeding, and dressing. Cognitive development during this period, framed through Piaget's preoperational thinking, reveals how children construct meaning through egocentrism, attribute life to inanimate objects, believe their thoughts cause events, focus on single attributes while ignoring others, and reason transductively rather than logically. Erikson's psychosocial theory provides structure for understanding toddler autonomy-seeking behaviors including defiance, emotional outbursts, and need for predictable routines, while preschoolers progress toward initiative-taking with emerging guilt and conscience. Play evolution from solitary parallel activities to shared associative and cooperative interactions facilitates socialization and gender role development. Anticipatory guidance for families addresses readiness indicators for toileting success, including neurological maturation and psychological willingness, alongside preventive dental practices targeting cavity reduction. Sleep disturbances require differentiation between nightmare and night terror presentations to guide appropriate parental responses. Comprehensive safety education encompasses proper car restraint selection by developmental stage, water immersion hazards, thermal injury prevention, toxic substance ingestion protocols, and firearm accessibility dangers. Language development includes recognition of normal dysfluency patterns, while disciplinary approaches emphasize consistency and proportionate time-out strategies. Routine developmental screening and early autism identification during preventive health visits enable timely intervention and family support.
