My LO gets aboit 4 bottles of EBM a day and now about 4 formula. I have successfully pumped since about two weeks but have noticed it is getting harder to get the same amount so i assume my supply is dwindling, Anyway LO was on Aptamil but ii had to change because of costs. we are on SUCH a tight budget a saving of £20 a month is worth it! i did all my research and went for HIPP. I have done it mega slowly-introducig 1 scoop a week and now for a 150ml feed she is on 1 scoop aptamil, 4 hipp. Her poo hs gone weird though. Usually yellow mustard-now she has a green poo first followede by a mustard after, and smells more like adult poo IYKWIM. Could it be the change in formula plus the fact that she gets less bottles of breastmilk? I'll probably go on full time FF soon as the supply is decreasing but dont want to upset her tummy? Anyone had similar experiences?
