My almost 4 year old was given a hand me down leapster that is on its last leg. The thing has a cracked screen and she only plays the games that are already loaded onto the machine. I was initially opposed to any screen time, but this contraption managed to see us through potty training. It was the only thing that was able to get DD to stay on the toilet long enough! I would like to get her a brand new leapster or leap pad for her upcoming birthday, but have no clue about the differences between all of the leap products. Does anyone have any recs for systems they really like? I am looking at the leapster explorer vs. a leap pad, but if anyone has an educational gaming system they really like I would like to hear about it.
