She would go nuts with it from time to time. She loved the thing until I got her an even better toy. The new one challenges (and entertains) her a bit more than the old one.
I have videotaped her going nuts. If I didn't put it away, she would play with it for hours and even in the middle of the night. She doesn't know when to stop.
Here are a couple of videos of her playing with her new improved toy. I am going to be off for awhile. In the meantime, enjoy watching Abby Gail play!
