Just let him try. I raised in mainstream school till graduated since the 4th grade because my parents refuse let me stay there because they plan to make me stay 3rd grade for another year just because of my age, I remember I was so down from attending to the mainstream school with the hearies and those deaf students who do the orally and hearing with the hearing aids, and have been begging on my parents to let me go back to deaf school. I remember I was crying many times, but till high school, I tried go back to the deaf school and they happened to not able to teach me because my level are too high for their school, but I went anyway for half mainstream and half deaf school and a few months later I decide to stay at mainstream school till graduated so I can keep my education up.
Sometimes I wish I stayed at the deaf school because of the communication and social stuff.
