DD received the LeapPad for her birthday. She plays with it a little. She likes the camera, drawing, and pet app that already came with it. We also downloaded Sugar Bugs (there was a choice of apps for free) and she likes it. She also likes the Dora cartridge, but isn't a big fan of Mr. Pencil. It goes through batteries quickly, so I would consider an adapter.
Re: Leap frog for 3 yr old B day?
DS is 2.5 and i got him a leap pad and he loves it. The games are kind of over his head right now but he has some apps he gets a lot out of.
