I took my toddler to this Webster Groves gym today for his first Tiny Tumbler gymnastics class, and it was a big hit. The class for 1&2 years old is not at all structured, which is appropriate for that age range. They spent a bit of time singing songs, but the kids really weren’t required to sit still, fortunately. Mostly it’s a just great place for little ones to run around and play in a safe environment with others their own age. One of the rooms even has child height high bars that they can swing from. It’s a little pricey(annual fee, plus fee for each 8 week session), but worth it to burn off some of that energy.
