Hi<br> Most babies tend to bite at the end of a feeding session when they are almost full. They might just want to play around and gnaw at your nipples.;When your baby bites, pull her off the breast and put it down. Do this every time she bites.;your baby is not latched onto your breast correctly, it is likely to bite your breast during feeding sessions.
