My baby hurts me! Help!

Ab

My baby always bites me while breastfeeding. I generally take the breast away let him cry a little and give it back and he won’t bite again.

But lately he has been pulling my hair, pinching me and biting me to the point where my arms are full of bruises from my little guy.

He will be 1 year old this Tuesday and I just don’t know what to do to make him stop hurting me!!! I have tried yelling at him to show him how mad I am but he just laughs.
