my daughter be 7 year old . she have autism . take care of a autistic child can be a challenge . once a day i allow she to play with she Nintendo d that I purchase from Amazon on line as long as she have good behavior . I allow she to play for a half hour . I use it as a way to reinforce possitive behavior . the add plus : this be my break time . autistic child sometimes focus on one thing and stay that way . they get really good at that one thing and that be all they want to do or talk about . I be very careful that she only play with it for that half hour each day . it be so easy to use and very portable . a must have for those long car trip or visit to the doctor . my daughter have become very good at she Nintendo d in a short period of time . I love it when she play with it because I get that half hour of uninteruptid time to myself . and that be a blessing to I ! thanks Amazon and thanks Nintendo !
