My DS seems to be extremly gassy while BF. After the first let-down once the milk slows down, DS pulls away from the breast. He screams and arches his back like he is in pain. Sometimes he passes gas just before or just after he pulls off but once he pulls off he won't relatch. I'm not sure what to do. I usually end of giving him a bottle of EBM to make sure he gets enough to eat. Has anyone else had this problem? I need some advice to help resolve this problem.
