It is really up to you. You could try it. I have a dd who did great in preschool she was reading and her teacher started pulling her and 2 other little girls who were close off for a little lesson each day. Nothing much but it was enough for her. She is really smart but doesnt like to show it off. She does things in her own time.
My other dd however hates to repeat things, couldnt sit still, didnt follow directions, acted out. I thought it was because she was 3 at the time so I let it go, Waited till Kindergarten 2 years later and got the same thing. She hates repeats.
One dd thrived, the other hated it. If you and your husband try it it might be helpful to see how it goes, but if not it sounds like he is getting lots of time with other kids in school like settings.
