We are kind of in the middle of the same thing except my son was in full day prek this year. The first half of the year he learned a lot about sitting still, appropriate behavior, standing in line, raising hands etc. once he learned those things he was bored and has now been transitioning to kindergarten. Next year because of our state requirements, he will have to be placed in kindergarten for 2-6 weeks and then will be skipped to 1st. If you think your child could benefit from K, you could always skip him part way through the year if he is bored. The only problem we had was that my son was hesitant to switch at first because he had made friends in his prek class, but now that he's done it, he loves it. The work is still easy for him, but he is definitely learning things and it's a much better fit. The kids are a bit more mature and he plays well with them instead of just telling the other kids what to do. He is also excited that other kids in his class can read, and they are learning things like estimation in math which I never really thought to teach him. Anyway hope it's helpful to hear our experience. My opinion is go with your feeling because you know your child best. Good luck!
