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. Birth weight typically doubles by 4 months & triples by a year. 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. Neuron: 1 of the billions of nerve cells in the central nervous system (especially in the brain)
