The nutritional composition of your milk will change over time to keep up 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.
