My mom just bought us a membership to the Kohl's children's museum, & I love her for it! When I used to go, it was in the city, but this one is in Glenview (I live in Palatine, & it's only 20 minutes away). It's bigger & better than I remember. My daughter is 20 months, & she had a blast! It's very low-cost & obviously kid-friendly. There are activities for babies & toddlers all over, & several nursing stations. There's a huge room to leave your strollers, coats, diaper bags, etc., or you can pay for a locker. You should check it out, & if you like it, you can get a membership so either parent, or the grandparents can get in for free. Good luck!
