Its so difficult to go out with Max since he refuses being breastfed(at home its super easy with no problem). I've had to give him formula when we go somewhere cuz when I pump its not enough breastmilk. I want to only breastfeed him but since he is used to be breastfed only laying down its difficult breastfeed him on my lap
