The Oswego Library has some great programs!!! Also, you can take the kids to Phillip's Park Zoo..that is free. They even have movie nights at the zoo. You'd have to check te City of Aurora website. There is also a place in Batavia called the Red Oak Nature center. This is also a free place. There is a bike trail that takes you down to a cave. Lots of cool things there. Lowes and Home Depot offer a free building project for kids on Sat. Home depot might be the first Sat of every month and Lowes might be the 2nd Sat. of every month...again, check their websites or call the stores. Batavia also has this Art in your Eyes event that is free. Kids can do all sorts of art projects. Really neat stuff. Check their website of when that is scheduled.
I'm a SAHM of 4 and run a daycare out of my home...always looking for free things to do!!! Hope this helps.
Oh, also, The Growing place off of Montgomery Road might have some stuff...I think it cst a little bit of money though.
Good Luck,
