My 4 years old plays Mario kart, snipperclips and Lego on the Switch. My children has also their own Nintendo 2ds. They have 2 versions of xbox, 3 different PlayStations and a WiiU. My 4 year old boy, can't play long. He is too nervous and he now it. If something don't go, he trow with his things. Can't loose games... My 6 year old daughter can play for a long time, but then there are days she don't even look to here handhelds and consoles. My 12 year old don't play much. She started at about 3 playing ln them. She don't like them very much.
