M.W.
My girl was a biter for a little while, but it only happened as she fell asleep, so I just learned to be quick with my finger. Eventually she stopped, thankg goodness, but not before I had a bleeder, as well. I absolutely could not feed her on that side for about three days; it was just too painful. There was no way I was going to try my pump, either. I hand expressed a few times a day, but mostly I was miserable.
Gosh, I hope someone else posts with some more constructive advice! :)
