OB, for what it's worth, PB went to Montessori at 2, I didn't have a choice, but I think it was the best decision I could make. Granted, she was 5 days/week, but for the socialization/stimulation/education I couldn't give her, I think it really did her good. Even if I didn't have to do it, I think I would have found her a 2-3 day program for those same reasons. And don't sell your mental/physical/emotional self short. If you aren't taken care of, you can't care for everyone else, KWIM?
