Music is always a common theme in kids toys, but it seems bigger than ever this year. Tiny Love's new Soothe and Groove mobile looks like your standard mobile, but when the your lil one is done with the moving parts, it detaches from the crib. It has a flip-up handle and turns into a tiny boom box for tots! Kidz Bop is extending its megapopular CD line to include everything from microphones and guitars to rock 'n' roll-inspired makeup, hair feathers, and clothing. And over at B.Toys, get ready for your lil ones (and their bigger counterparts) to start composing their own music with Symphony in B, a system that introduces kids to the sounds made by the instruments in an orchestra — trust me, it's amazing!
