I think this is a nice idea, but they probably have a lot of stuff already. Just a thought from somebody who has had babies.
Especially for girls... People love to buy things.
So here is an alternative idea... My two cents if you will... How about a little baby shirt with a cute saying on it, possibly drumming related? Or one with a downhere logo on it? I think somebody did that for one of the dh babies a while back.
