My baby almost got bit

Vanessa

At daycare. 9 months old. In his own crib. They put a known biter in with the babies because the ones room was over ratio and he was the youngest by a month. I work there and was looking over the wall because I asked them to start putting him in the crib at 10 and maybe he will learn he needs to sleep. So the biter walks over there and my baby doesn't know any better sticks his hand out and the kid goes to bite him. Like excuse the language WHAT THE FUCK?! I freaked out so hard. I almost grabbed him and left. I understand little kids bite. But this is a known biter in with innocent little babies. My son was in his own crib minding his own business and almost got bit. I was so terrified of putting him in daycare and now I'm honestly not taking him back. I am in tears y'all? Am I overreacting? I could understand if he had a toy and my son took it. But the biting is out of control in daycare. I don't understand why they are allowed to stay if the repeatedly bite other kids.
