C.K.
My son only bit after he was bottle fed for a week at about 6 months. So, I would say NO very firmly...this would startle him at times where he did not want to eat the rest. Since this only happened about two or three time in a day or two after going back to breast feeding I was not really worried that he would not finish eating. We just picked up the next feeding.
Hang in there if you are firm it should not take but a couple of times.
