Breastfeeding and started biting 😦

Brittany

My son is 7 months and he is exclusively breastfed(no bottles or pacifiers). He has a total of 4 teeth (2 bottom popped through at 4 months and 2 top at 6 months). He's been very good about not biting my nipple until recently. he started biting me REALLY HARD! Its gotten to the point where I'm terrified to feed him Hahhaha. Any other mommas dealing with this? And if so, any pointers on how to get him to stop???
