I have been breastfeeding since birth and thought everything was going fine until his 2 week apt last week when they informed me he still hasn't gained any weight. My son was born at 8 lbs, 13 oz and left the hospital at about 8 lbs, 3 oz. He currently weighs 8 lbs even and has since his one week follow up at Great Beginnings. He eats good-they say he is latching on great and he eats about every two hours except at night-it's about 3 hours or so. He is pooping-almost after every feeding even. It's mustardy, seedy, and pretty loose. He has plenty of pee diapers every day. My husband is active-duty so we must see the base pediatric clinic-but the person we saw was a P.A. and she wanted me to supplement with formula-she actually wanted me to go straight formula but I put up a fight. So she is saying I need to pump and give him between 16 and 24 oz a day, so if I am not pumping that much, then to supplement with formula the rest. I am doing that for the first time today and so far, we haven't given any formula. I am really having a hard time with this b/c I don't want him to get use to a bottle and formula and then not go back to the breast. Of course, I feel like failure as a mom, since I can't produce enough milk for him to gain adequately. They have me taking fenugreek and they have done all kinds of blood work to make sure nothing else is wrong and that all came back normal. Do you have any advice that might help? Is it possible he is just a slow gainer? He has really explosive diapers pretty quickly after he eats and someone mentioned maybe he's lactose intolerant and he can't tolerate my milk, so he is getting rid of it all so quickly he's not getting the nutrients he needs...is that possible?
