I switched my younger DS out of his daycare when it got way too academic too early. He hated that (at age 3.5) he was expected to sit long periods of time etc. and his behavior at school and home was suffering. Also, the discipline was too strict for that age. I switched him to a 1/2 day, almost all outdoor preschool. His behavior got way better, kids had a lot less conflict being outside, and he did great in K and now in 1st grade. The teachers at the preschool also saw this as a career, his daycare had awful turnover. Older DS went to a smaller in-home in a different city and that was a positive experience.
