Colostrum is baby’s first food! It’s a thin, yellowish fluid that your breasts produce at birth. In fact, you may have noticed some of it  leaking from your boobs toward the end of pregnancy.

Colostrum is full of proteins and antibodies to help baby build her immune system, and it’s all baby needs to eat in her first three to four days. After that (as long as you keep breastfeeding, your body will start to produce breast milk.

One of the coolest things about breast milk is that it continues to change over time. At first, it’s thin, watery and sweet — mostly a thirst quencher (with sugar, proteins and minerals) — and over time, it becomes thicker and creamier to satisfy your hungry baby.
