Try eating stuff to produce lactation. I know oatmeal is really good for that but look up other things that can help. My sister had problems with that as well. Talk to your obgyn about it as well
I had the same problem with my first. It took sooo long for little milk to come out of my breasts. Then I tried taking Moringa herbal tablets, eating a lot of soup, and warm compress my breast et viola! Milk came! Hope it works out for you.
P.S. always talk to your doctor first
