firstly excuse typing but on phone. ds2 is 3 weeks and so far breast feeding going very well, after failing to manage it with ds1 i was really pleased. since about 3 today every time he feed's he is on the breast for 5 minutes then screams, shakes head and becomes very distressed, as do i! any idea's, have winded lot's in case it's that. getting all upset that i might not manage it again and am panicking that he's not had enough. tried expressing but my pump don't seem to be working like last time. help please?
