Document Summary
Psy dev 307 infant development review 2016 van widenfelt. In the early months, most of the newborn"s weight gain is fat. Infants typically double their birth weight by the fourth month and triple it by age 1. By age 2, body weight has increased to almost 28 pounds, almost a fifth of their adult weight; body length has increased to about 34 inches, almost half their adult height. A newborn"s brain weight is about of an adult. If children are malnourished, head-sparing is the phenomenon by which the brain continues to grow even though the body stops growing in a malnourished child. Throughout childhood, regular and ample sleep correlates with maturation of the brain, learning, emotional regulation, academic success, and psychological adjustment. The average newborn sleeps about 15 to 17 hours a day. Traditionally, the children of western parents sleep separately in a crib. Co- sleeping (infant in parents bed) is practiced in asia, africa, and latin.
