Review on Exploring the World: NATIONAL GEOGRAPHIC Stepping Stones for Kids – 10 by Eric Timbeross

They seemed great, colourful, light and easy to use. But every time we used them, they were so light they slipped out from under our feet when the boys tried to step on them. We have two and four year old grandchildren and wanted to play hot lava, play crocodiles in the water and find some balance. They just added frustration as they don't stay where you put them and end up being kicked around the playroom and used as a frisbee, which isn't great in these little ones' hands. So I return them and get weighed. Plus it's insanely ridiculously overpriced for what it is! They are mostly made of the same material as foam pads that fit together like pieces of a puzzle.
