Biting baby

Kristen

Hi all, my little girl is 5 months old and has her two bottom teeth. Just this week she has started biting me...hard... when she does I unlatch, say ow, we don’t bite and then relatch. Anything else I can be doing? It has gotten to the point where I am so tense while I’m feeding her because I’m afraid she’s going to bite me, which I think effects my milk flow to her. She got her teeth so young I don’t think she understands what she is doing. Thank you!
