Well, sometimes you gotta restrict the amount of play-time a child can get..

I don't know what kids want these days, but I do see alot of kids holding on to GBA advance/SP's.. have no idea what they're playing.. Most likely something like Pokemon and Megaman Battle Network..

So what I'm trying to say is.. A GBA should do the trick, just get a nice game to go along with it, or not the GBA will be thrown down the thrash..

And oh, there's this neat little game called "Warioware: Twisted".. I think that should be fun for his age.. Something like RM150 last I checked from Gamers Hideout.. Nintendo counter may have a few units too.
