GPs brought son (7yrs) a Nintendo DS for Christmas - against our wish - I hate the thing, we're a very low screen time family. children do watch tv etc but minimum amount. He loves it and I don't want to take it away completely, but when he's playing it he is so immersed and ignores rest of world completely. Is 30mins on it a day ok? - I'm hoping by not taking it away completely he'll tire of it.
