When Will My Baby Start to Gain Weight?

Most babies lose up to 10% of their birth weight in the first 4 days after birth.  Your baby may lose a little more if you were induced, had intravenous fluid, an epidural or a cesarean birth.  In these first few days, your baby is learning to coordinate his suck, swallow and breathing.
 

Have your baby's weight checked by the doctor or midwife 1 or 2 days after you go home.

Most babies start to gain weight by day 4 or 5, after your breasts fill with larger amounts of milk.

Babies are back to their birth weight around 10 to 14 days of age.
