Document Summary

Growth is so rapid and the consequences of neglect are so severe that gains. Newborns lose a bit of weight in the first 3 days, then gain 30 grams a day for: birth weight typically doubles by 4 months and triples by a year. Physical growth in 2nd year is slower but still rapid. Early check-ups are vital because abnormal growth may signal a problem. Prenatal and postnatal brain growth (measure by head circumference) is crucial for later cognition: head-sparing: a biological mechanism that protects the brain when malnutrition disrupts body growth. The brain is the last part of the body to be damaged by malnutrition. From two weeks after conception to 2 years, the brain grows more rapidly than any other part of the body o. Communication within the central nervous system (cns), the brain and spinal cord, begins with nerve cells called neurons.
