Hey mamas, FTM here. I am currently pumping and adding some formula to my breast milk to help my 4 month old gain a little extra weight as he isn't where the Dr's would like him to be. My milk supply seems to be slowing down and I'm getting really sad about it because by baby hardly likes it when i have to keep adding more formula to the breast milk so if I have to go to straight formula I don't know what to do if he doesn't want it. Right now we are using nestle good start. Now that I have added more it seems he doesn't want to drink too much. He seems to not like it. What formula have you used and which ones are the best? Please help!
