I am not sure that is too early, of course it depends on the child and the school/teacher. Many preschools are less age oriented than the older grades, we are in a program which mixes from age 3-5 (supposedly, although I just found out they weight one classroom with more younger kids and the other with more older kids).

The language stuff seems to be less clear/more varied with kids than the math; I do think counting that high at 2 is very unusual!

Welcome to the board, I hope you find some good info.

I am still working on my dd4's possible admission to K, will post more when I get some feedback from the school.
