Hi girls, anyone's baby fussy while feeding? Maybe I'm not attaching correctly? How can I attach it properly? He refuses categorically from me. I don't have any discomfort in my breast, it doesn't hurt or crack, milk is flowing. But yesterday my son had bloating of the stomach, he cried because of this and because of hunger, even lost his strength. I felt awful. Help with advice ????
