Document Summary
At 24 months: 28 pounds: average length. At birth: 20 inches at 24 months: 34 inches: these numbers are norms or average measurements. The rate of increasing weight in the first weeks of life makes it obvious why new babies need to be fed day and night. Where should babies sleep: u. s. middle class infants sleep separated from parents; sleeping patterns are changing, decision to co-sleep or bed-share linked to culture, age of infant, mother"s education level, depressive state, and father involvement. Asian, african, and latin american infants co-sleep orbed-share. Asian and african mothers worry more about separation; european and north. American mothers worry more about lack of privacy. Prenatal and postnatal brain growth (measured by head circumference)is crucial for later cognition. Head-sparing is 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.
