My 9 week old dd is feeding well, she's currently gaining just over a pound a fortnight, so im really chuffed with that, im ONLY breastfeeding - no formula top ups or anything, but in the last few days maybe around a week now, she has started to seriously wriggle and cry half way through a feed, she kicks and punches vigerously, pulls herself off the breast and yells, she seems angry/frustrated/upset, i know its not supply as i have quite a good supply, ive switched sides and she does the same within a couple of minutes. I eventually stick her dummy in and she calms down, have done this 10 mins ago and she has gone to sleep all calm again. Any ideas whats annoying her??? Ive no clue.....
