Query: Son Loves It

My 6 month old son really enjoys this ball. It is interesting and rolls on its' own, keeping his attention. My son is just starting to scoot around, so this ball motivates him to get moving.One thing I don't like about the ball is that it is weighted and hard to roll the way you would roll a regular ball. I guess that comes with the territory when you have a ball that does its' own thing, but I'd also like to be able to roll it back and forth to him.
