Last week most of the moms were very anxious about why does their babies bite during breastfeeding sessions.
I just gave a few tips on that. Hope if I share it here, it reaches most of the moms and will be of more use.

Suggestions are always welcome, it helps us answer the questions better.

It is due to improper latching position. Make a comfortable feeding position and Get his/her mouth to open wide and push your nipples till your areolas are in his/her mouth. This will give your baby better reach to latch and avoid hurting your nipples.
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 does it.
When your baby is teething, the irritation in its gums makes her want to chomp on anything that she can put into her mouth.
These are the few reasons why babies bite on nipples.
