P.
I use the Leaning Tower YMCA on Touhy. They have a playmaze similar to those at some McDonalds and they also have a TV and a play area with toys and coloring. I have 3 boys - 6, 4, and 2 and they all love it. In fact, they ask me to go there even when I'm not working out. Family membership is $65 per month and includes the childcare.
Good Luck.
