I just had my third child. He was a repeat c-section. I breastfed my other two just fine. I seem to not have enough milk coming in for this child. He is five days old. I let him feed as long as possible and even tried to pump after him but my milk will not increase. I give him formula after letting him nurse so that he does not feel hungry. I really don't want to do that. I feel like I should give up on nursing because I can't give him enough milk. How long should I go on trying to feed him? Breastfeeding means the world to me.
