What do you mean he hasn't been socialized? Have you taught him not to hit, fight, bite, or be mean to YOU and the other people in his life?
If you knew he wasn't capable of being around others without being physical then you knew he couldn't manage little children.
It's your job to teach him to obey adults, follow directions, be patient, and keep his hands to himself. Have you done that? A child care environment is where the skills you have already taught him get fine tuned NOT where they are first learned.
Take him out immediately for the sake of the other kids and the adult caregivers. Do it for them. Don't worry about what is best for him, you, or your family. Think COMMUNITY first.
