If your son is only 2, and you can stay at home, he doesn't really need preschool, and it sounds like he's not ready. I agree in principal to the previous advice and that definitely applies. I had my middle son in preschool at 3, like his older brother who did well. But it went badly. I felt it was necessary to socialize him and I needed the break, but he really suffered. I kept him in thinking he'd "get better". He still has some anxiety issues and we had 2 very bad years in 3rd and 1st grades. He's 11 now and doing fine, but I wonder if I'd let him pace himself if he wouldn't have matured emotionally a bit more stable. Maybe not, but you shouldn't think you have to send him. You could socialize him at a play group or something where you can observe him and start to understand his patterns.
