Maya'a revenge

We have been telling Lauren she needs to stop picking on Maya but it just never sank in. Well today she was taking toys and books, etc. off her and Maya had had enough. She DID warn Lauren but repeatedly saying no but Lauren wasn't hearing it and so Maya turned around and bit her. It was a superficial bite but it was enough that Lauren backed off! Lauren cried and Maya was told our teeth are for food not people. They are steering clear of one another tonight.
