Xbox 360 Video Games for Pre-schoolers

My 4yr old loves playing games on the computer, but I need and want my computer throughout the day. I searched for xbox 360 games for pre-school and found these links.

Common sense you can actually search by age. But alas, none for xbox. Only for wii and nentendo DS.

Wii has sooo many pre-school games. Which is great, if we had a wii. Seriously xbox needs to get with it.
