My son has autism and insists on watching the same gaming YouTube videos over, and over. We don't have gaming devices or even a tablet he can use in the house as they increase his tics and he becomes 'wired' in a way normal tv doesn't seem to affect him. The YouTube videos have the same reaction and I'm really worried about the effect watching gaming YouTube videos has on his symptoms. I'd like to have some control over if/when he watches it (ideally I'd remove it completely) but can't see a way of restricting time on YouTube, or even to add a parental restriction code so that he would need me to allow access. Thanks.
