My baby girl is super active as well... if she knows the place,she will crawl away from me, and play with whatever she finds.... and she never stopped, and is OK with noise.. a friend ofmine of a 11 months baby boy, and she can't turn on any toys with music on, because it scares him...
I hope she won't be too active when she grows up.. of else I will have to chase after her everyday, haha
