Ahhh well keep in mind his tummy is only the size of a marble... So he's not currently needing a lot. But you can try fenugreek or mothers milk to boost supply but that may hinder his latch when he's able to nurse because the flow will be too much
my son was born at 32 weeks he can't take Formula right now @dcb012
Why are you pumping at 32 weeks? Are you nursing an older one?
he is in the nicu he has to use feeding tube I have to pump milk or he will have to drank donors milk and I really don't want that
