Ds was playing Thomas the tank engine and other pc games at about 3.5. I remember he just loved it, no negative affects that I am aware of. It was a nice arena to express his abilities with shapes, color, etc. as those games were educational. Just a week ago I found his old leapster and dd has now claimed it. I am surprised she is getting pretty good with the pen and putting together the shape drawings. I would be interested to find out if letting her on the pc is bad.
