Document Summary

Physical development in early childhood: body growth. Individual differences in body size are even more apparent during early childhood than in infancy and toddlerhood. The existence of these variations in body size reminds us that growth norms for one population are not good standards for children elsewhere the world. The skeletal changes of infancy continue throughout early childhood. By the end of the preschool years, children start to lose their primary, or baby teeth. Girls do this sooner than boys (girls are ahead of boys in physical development). Cultural ancestry and nutritional factors also make a difference. Prolonged malnutrition delays the appearance of permanent teeth, whereas overweight and obesity accelerate it. Between ages 2 and 6, the brain increases from 70% of its adult weight to 90%. At the same time, preschoolers improve in a wide variety of skills physical coordination, perception, attention, memory, language, logical thinking, and imagination.
