Query: Favorite toy, right now.

My 8 month old loves these things. I can't comment on how much she's learning but she really enjoys banging them on the floor and on themselves, hearing the noise and seeing the colors change. These things are durable for sure. She bangs them, chews on them and drops them on hardwood floors. I now have the darned voice in my head though, "Shake it up!" but I'll live. :)
