LO got a leap frog tag junior system for her first birthday. It was never something I even thought to get for her, but it's pretty cool. She only has a couple of books for it so far, but she can't really figure out how to use it yet anyway. Does your LO have any of the reading systems (even a brand other than leap frog?) what do you think of them and when could your LO start really understanding how to use it?
