So I breast feed and formula fed my baby but now she dosent want to drink formula at all she gets mad and closes her lips real tight and wont drink it im so scared she’s not eating enlightened nutrients I breastfeed her all the time but with the formula I knew she was taking exactly what she needed I also give her alittle bit of gerber what should I do? Has this happened to any of y’all and how did y’all handle it? Any tips?
