Anorexia The amount of milk consumed by newborns changes significantly within 1 week after birth, for example, they may only need 30-50 ml/kg/d on the first day after birth, and then gradually increase, reaching 120-150 ml/kg/d after a week, and then maintaining a relatively stable amount of milk. Therefore, determining whether the milk quantity is appropriate is related to the postnatal day age. The amount of milk can vary throughout the day at each feeding and the interval between feedings may vary from 2 to 6 hours (depending on the infant’s sleep and activity cycle), but the total amount of milk does not vary greatly from day to day. The amount of milk varies from infant to infant and is related to the baby’s activity, sleep, and individual differences. Therefore, to determine whether an infant is getting enough milk, or to worry whether the baby is anorexic, you should not simply look at how much milk is given each time, but also at the baby’s growth and whether the mental condition is good. 1.What is anorexia in newborns? (Why is it anorexic?) Anorexia in newborns can be caused by many pathological reasons and requires a thorough examination in the hospital before a judgment can be made. Case BOX: My son and my neighbor’s daughter were born on the same day, but their daughter eats milk every 4 hours, while ours is a boy, but not as much as a girl, and only eats every 5 or 6 hours. 2. How can I tell if my baby is anorexic? Normal newborns will show active food-seeking movements, become alert, increase physical activity, increase facial expressions and even cry when they are hungry, suck forcefully and swallow well when feeding. The interval between feedings is related to the amount of milk and the sleep cycle, generally ranging from 2-3 hours. If the baby lacks the normal reaction mentioned above, and sucking is weak or refuses to eat, or the amount of milk does not reach the normal amount needed, then it can be considered as bad milk eating. 3.What should I do if my newborn is anorexic? Temporary lack of milk, but good mental condition and normal growth do not need to be treated, otherwise, prompt medical consultation should be made.
