i expessed before DD was born and got heaps of colustrum and then was worried that I wouldnt have enough for her but your body will produce more colustrum when your bubba is born. Your baby's stomach is the size of a pea when it is born so they dont need alot, it then grows to the size of a marble I think on day 2-3 and keeps getting bigger when the milk comes in.

You will be fine
