My 9-month daughter loved a friend's teether that looked similar to this. I bought it in a store, but it turns out that she can't get the teether nubs to her back teeth. The ball is too hard. We were at a BBQ and everyone was laughing at how disinterested she was in this toy. I should have waited and looked on Amazon for the same one. Now I'm buying the second teether. This was a waste.
