My 3 week old baby has started getting fussy during feedings. She first struggles to latch on...then she sucks a few times and starts pulling back. She'll breathe fast, flail her arms and legs, pull back, and keep relatching. It's frustrating for both of us. She doesn't do it all the time, but I've noticed it more yesterday and today. I'm sure she's getting milk because I can express some and I'm leaking. I also feel the letdown.
