I have two girls, perhaps 8 months and 3 months old, and I recently got them a Kaytee 12' silent spinner wheel. Neither of them have ever seen a wheel before and mostly they try to pile bedding in it, move toys into it, etc. I've tried putting them on it and moving it gently to and fro to give them the idea; they definitely can get it to move and everything but once I move away they abandon it. Is there a better way to educate them on how to run on the wheel? Or is it just not their thing?
