First time mom here. Our son is 3.5 weeks old. At our first doc apt we had to start supplementing because baby lost 10% of birth weight. Since then I have been mostly pumping because it's easier to make sure I'll have something to give baby when he's hungry and because I'm able to tell exactly how much he's eaten. Since Friday I've been trying to nurse exclusively and it's going terrible. Baby latches on but falls asleep after 10 mins. I burp him, change a diaper, and switch breast and try again, 10 mins later he's asleep again and I do it all over again. I go through this process for about an hour and then put him down and pump for 15-20 mins. When he wakes up fussy/hungry 15 mins later I give him the little I pumped and then formula until he is satisfied. Sometimes however, he gets extremely fussy while I'm trying to nurse him. With my breast in his mouth he is crying bloody murder. I don't understand, my breast is there, I see milk, I switch him sides, and still he is crying his lungs out. At this point my husband says that he is going to make him a bottle. That he is crying because he is hungry and I'm being selfish by starving him just because I want to breastfeed him. He says all that matters is that the baby is fed. It breaks my heart/pisses me off how unsupportive he is. One I have no idea why baby gets like that and two I don't know what to do with my unsupportive husband. I have a fourth apt with the lactation consultant in a week. Any advice is much appreciated!
