Re: Nursing strike
My DS has struck for a day or so a couple of times. It is difficult not to panic about it. Don't blame yourself about the biting and unlatching--you can't allow her to bite you and still have a good nursing relationship! My DS reacted a bit that way when I yelped after he bit me once, but he got back into nursing.
