My daughter is now five weeks old. She is the third child I have breastfed. Starting on Saturday, she starting acting weird during nursing. She nursed on one side just fine. I burped her and changed her and we started on the second side. I put my nipple in her mouth for her to latch on and she started freaking out. She was screaming at the top of her lungs like someone was killing her. I checked to make sure nothing was physically hurting her. She would not calm down, so I had to push on her chin to get her to finally latch on. Once she latched on, she was fine. She has been doing this now about every other feeding and it doesn't really matter which breast it is. Has anyone else had this problem? Can anyone give me any info on what to do? I am about ready to give up on BF and just give her bottles.
