I have a similar experience with my 5 week old. Weight gain/diaper normal. If my DD is bobbing on and off the breast, punching, crying, do I just keep going even if she is not even really sucking/swallowing? Does this apply only if it appears that there is no milk? What if there is milk when I express or if my breast is actually leaking when she fussed off, would that be a different problem?
