Our district has a toy library that is run through the Success by 6 program. It's great! We can get 4 items and they are due back in two weeks. Yesterday I got some duplos, a hammer/ball toy, a stand-up walker for toddlers, and something else that I can't recall right now.
Anyways, just thought I'd mention it here - you might check with your district to see if they have one. We love it!
