Does newborn get enough to eat?

A

Im a STM. But I have some questions..when my son was born, I tried BF but he couldn’t latch so they had me start pumping in the hospital and between both breasts I wasn’t even making a ml. Sooo if I wouldn’t have used the formula that the hospital provided, how would my son have had enough to eat? I plan on trying to BF again this time around but I’m worried about milk not coming in
