This has been a long road but I think I have exhausted all other options. My ds was born at 8 lb. 11 oz. and gained well the first two months. At his two month wbv he was 11 lb. 2 oz. which was decent and definitely didn't cause any reason for concern. The trouble happened when at his 4 month wbv he weighed in at 11 lb. 4 oz. My son's ped. has been wonderful through all of this and didn't even hint at formula but did suggest that it was most likely due to low caloric intake. He recommended a few things like having his pre- and post-feed weight taken, see a lactation consultant, etc. I use a nipple shield when nursing my ds and he will not latch on without it so far so I believe this has been at least contributing to low-supply issues. So we saw a LC to try and get him off the shield to no avail. Hind sight is 24/7 but I wish I would have never even given him the nipple shield because it's caused way more problems than it has solved but I was feeling a lot of pressure in the hospital to get him to feed. (Yet another reason why my next will be a home birth!) I have been taking him in for periodic weight checks and just last week when he was weighed he lost an ounce! It is so frustrating to be trying so hard and nothing seems to be helping. I have been popping fenugreek and blessed thistle like crazy too. It doesn't help that my sister had a baby 7 weeks after me and her baby has already surpassed mine by several pounds. I'm not sure exactly by how much but it is very obvious by at least 2-3 lbs. My ds ped. has another family in his practice in the same boat as us and he recommended that baby see a cardio specialist based on another symptom she was having and told me he would call me to let me know if they found anything out. Well he called me yesterday and said the cardio specialist did not find anything wrong with the baby's heart but that the baby was going to have to be hospitalized. I am freaking out. I asked if their case was more extreme as ours and he said no that we were both in pretty much the same situation except that the other baby won't take a bottle at all. My ds has taken bottles of EBM so I know that is not a problem for us. I DO NOT want my ds to be hospitalized! Especially since he isn't vaxed. I feel so defeated and that our only option is to supplement with formula. I only want to use this as a last resort and would never use it for convenience but my baby's health is on the line now. This has gotten to be a long story and there is so much more to it but I guess the main reason why I was writing is to just make sure I'm doing the right thing. I will be pumping like crazy to get my supply back up so that the formula is only temporary but any words of wisdom or advice would be much appreciated. I also would like to know if anyone has supplemented what kind of formula they recommend.
