You might have heard that when the first teeth appear, biting during breastfeeding starts too. But here is an interesting fact: while the baby is actually breastfeeding, they cannot bite you. During sucking, the tongue lies over the lower gum and teeth, if they have any, protecting the nipple.
So when does the bite happen? Usually when the baby stops feeding actively. It can happen at the start or end of the feed, when the milk flow slows down, when they are already full and start to play, when they are distracted or seeking your attention. The appearance of the first teeth can also contribute: if their gums are uncomfortable, biting can provide some relief
