So my boys keep eating/ chewing holes in nipples they are like 11 or 12 weeks old and I have weaned them to eating 2x a day due to my pregnancy situation. Tonight I didn't have a nipple to feed with to I tesed my theory of putting the formula in the bottle feeder it seems to be working great but I cant monitor/write down how much each is eating...what should I do or at this point tracking doesn't matter??? They are all pretty much 1lb one is just a few gs shy
