My mom said to bite her back too. I just don't know. I might have to. It hurts. Lol. And she's left a bruise on my leg and a mark on my collar bone. I have to be careful on how I respond to certain things being as Im bi-polar, and have a lot of anxiety. Lol. So I usually smack her on her butt and put her in her very empty play pen.. Just that makes me feel bad, she's only 8 1/2 mo old.
My oldest son I was told to bite him back and he would stop. I felt bad and didn't want too then one day he bite and brought blood to the surface and I told him he was gonna feel how other felt I Bite him on the tip on his finger and that was it.
