Baby Weight Gain: What Helps And How

How much should a baby weigh after birth? New-born weight after completing a full term normal pregnancy (38 to 40 weeks) usually ranges between 2.5kg and 3.5 kg. Premature babies and babies who have growth retardation in the womb weigh less than 2.5 kg. The weight of the preterm baby varies with the extent of prematurity.

Various factors in pregnancy such as the mother’s health and nutrition, blood pressure and diabetes in the mother, chronic diseases  premature delivery, a twin pregnancy, genetic problems, etc. have a significant effect on the weight of the baby.


A normal full-term baby loses some weight (5% to 10%) in the first week after birth. It takes around 10 days to 2 weeks for the baby to regain the lost weight. A preemie or weak baby takes 2-3 weeks  to regain its birth weight. Weight lost in the initial days after birth occurs due to loss of fluids from the baby’s body.
