For mothers who intend to breast-feed, nursing is one of the first things that happens after baby enters the world. Right there in the delivery room, you'll put the baby on your breast for the first time.
There's no real milk at this point, though. For the first few days after delivery, the substance your baby is drinking is colustrum, an extremely digestible, thick, yellowish substance that carries essential antibodies, proteins and energy stores to your newborn. Only tiny amounts come out, which lets your baby practice feeding before the real milk supply starts flowing.
Some moms worry their infant isn't getting enough to eat, but this is all completely normal. Typically, mother's milk starts filling your breasts (and the baby) anywhere from two to five days after delivery.
