with Baby's nutritional needs. The first few days after he is born, instead of
what you might usually think of as milk, you'll actually produce a fluid called
colostrum that is rich in protein and antibodies. It will help your baby's new
digestive system function properly, pass along immunity, and help him gain
weight. In just a few days, this colostrum will transition to mature milk, first
thin and watery and then thicker and creamier. As you continue to feed your
baby over the coming months, the composition of this milk will continue to
change, providing just the nutrients that Baby needs at that particular time.
