Disney Dreams, Golden Mickeys, Hercules are all great for little ones. She might not understand the whole show and all of the dialogue, but she will still enjoy it.
Beware - My DD, 3 and 4 fell asleep in every show we took them to - even at the matinees. The dark room and the comfortable seats, sent them to la la land, and to a much-needed rest. Be prepared to carry her out of the theater.
