PSYB20H3 Chapter 5: PSYB20 Ch. 5- Physical Development and Health, Birth to Age 3
Document Summary
5: physical development and health, birth to age 3. The first three years are a time of explosive growth and development never again will a person grow so quickly or change so rapidly. An infant"s head is huge compared with the rest of the body. If you had the same body proportions as an infant, your head would be the size of a watermelon: this characteristic highlights the cephalocaudal and proximodistal principles of early growth and physical development. Growth is faster in the first few months of life than it ever will be again. Babies continue to grow super-fast during the first two years, tapering off after the third. Boys and girls show similar patterns of growth: boys are generally a bit heavier and taller than girls. As a baby grows into a toddler, its body shape and proportions change too.
