If you are happy and he is happy, keep him home, its great for him But if you think he would love it or can help him then it might be something to consider. It was an easy decision for me, Marisa was 3, turning 4 in April so I sent her and she was fine. Elijah is 3 this year and will go next year, but I have a feeling he isn't going to have such an easy transition, he's more clingy, as boys often are!
