Thanks apples and bananas, that's my thought. I have been shadowing him since the first incident he always does it like with my son when I was changing a diaper, or with my daughter when I ran to get a diaper for another child. I saw him grab her hand and said his name and no in a stern voice but he did it anyway. I'm getting close to terminating cause I can't have children go home with bloody bite marks. But they were willing to work with me except bite him back to show him it hurts. Ugh
