So I've been exclusively pumping for my little man since after a few lactation consultant visits and a month and a half of trying we stopped trying to BF. We originally had to supplement with formula (my supply was down, but now is ok) and he was extremely gassy, so we switched to dr brown bottles and I quit drinking milk and it got better. I started to gather formula of a few different brands from free samples and buying some cheap on varagesale. We slowly started to transition him over to formula, starting with one bottle of formula and the rest breastmilk and we've slowly increased the amount of formula to breastmilk. We currently do 4-5 breastmilk bottles and then 3 formula bottles. (I freeze extra right now so I can hopefully quit pumping in a month or so) He doesn't seem to mind eating any of the various formulas, but the gas has become a problem again, which I stupidly thought was solved earlier. We're doing Similac Sensitive now, which seems to be going better, but he's only been on it for 4 days. I also thought his digestive system was supposed to be more mature at 3 months and he's almost 4 months. So now I have a large stash of formula that most of it it's looking like I can't use.
Do you think his digestive system will get better and I can possibly use it in a couple of months? Or could I try to use up what I have doing like 1 scoop a day? Or should I just try to trade & sell what I can't use?
