Query: Wow! Our son loves this mobile.

We bought this mobile after seeing it in the store, and we're very happy with it. We bought it when our son was about 3 weeks old, and he immediately loved it. He's now 5 weeks old, and likes to lay in his crib and make noise at it. It's very stimulating for him, even if you play the Bach, which is recommended for calming them, so that's something to be aware of. (There's no way he would fall asleep watching it - as he watches it, he gets more excited.)We haven't had any issues with the motor or any noise concerns, and are perfectly happy with it.
