As the father of a boy with an ASD
Autistic children have problems interacting with others, partly because they don't understand others or the rules of interaction, partly because trying to play by the rules of social interaction is tiring and stressful ...
Even the most adjusted kids with an ASD (Autism Spectrum Disorder) need timeouts or space to not be on guard all the time.
Another big thing about kids with an ASD is the obsessions that they have, you might imagine that you have a fixation on something or someone, but for them it's a case of every breath, every thought, every word is targeted ... It can be very hard to get your child to do anything but that obsession.
Having said all that my son has to be watched because he can turn aggressive if not given strict times that he is allowed on to the computer/console ... we used to have to physically restrain him when removing him after 1/2 hour of play time so that he didn't hurt himself or the computer that he was using.
Knowing that he has a fixed limit of play time (using a timer that he cannot change) and him being a bit older means that this problem is much improved. Asking _him_ to turn off the computer is much better than _me_ turning off the computer as it leaves him feeling in control.
Having set limits on time (50 minutes is a kinda maximum before he gets grumpy) and appropriateness (not before bedtime, not when he's tired) and, unlike the mother of this child, I will not let him play on anything above a PG ... he is only 10
Hoepfully that made sense and wasn't a general ramble.
