Thanks Barb, I think you may be onto something there... I have been so much in the habit of feeding often to try to get my supply up that now it's improved I probably should have pulled back a bit. I just didn't see the wood for the trees. I just fed her (after waiting for her to come to me for it) and she didn't bite. I'm still nervous with the really sore side, and took her off a couple of times when she took a pause in gulps, which she wasn't too pleased about but she was very gentle.
