Document Summary

In infancy, growth is so rapid & the consequences of neglect are so severe that gains are closely monitored: medical checkups provide 1st clues as to whether the infant is progressing as expected. Body size: weight gain is dramatic, birth weight typically doubles by 4 months & triples by a year, avg. pound newborn is 7 pounds, physical growth in the 2nd year is slower but still rapid. By 24 months, most children weigh almost 28 lbs. Should be 34 inches at age 2. Norm: an average/standard, measurement calculated from the measurements of many individuals within a specific group or population. Genetic diversity means that some perfectly healthy newborns are smaller or larger than norm: prenatal and postnatal brain development (measured by head circumference) is crucial for later cognition. Head-sparing: a biological mechanism protects the brain when malnutrition disrupts body growth. The brain is the last part of the body to be damaged by malnutrition.
