My 12 year old son with ADHD has difficulties with self control. I have taken his phone away as a punishment and he has taken it when I didn't hide it. Also he has taken out his school computer to play games while he was supposed to be going to sleep. His reason is because he's not tired to go to sleep at 9pm. He knows he is not to use electronics at night specially when is time to go to sleep. I feel that punishment doesn't work. I can use suggestions on how to address him defying our rules. Thanks from a new mom about ADHD.
