I can’t speak to classes that are taught here, but this facility does offer a great «open gym» specifically for pre-schoolers on Tuesday and Friday mornings. For all of $ 5 for the child(and free for accompanying guardian), your little one can spend an entire hour walking on balance beams, jumping into foam pits, bouncing on trampolines, and doing all sorts of things to burn energy. This is particularly appreciated in the MI winter climate when going outdoors often isn’t a reasonable option. They do also offer packets of discounted passes — I think it’s only $ 15 for a pack of 5 passes, making it an incredibly reasonable $ 3 per session. The location can be bit difficult to find, particularly because the building has a parking lot both in front and back. Best to call for specific directions.
