I made DS1 (now 18) wait until he was 16 to play 18 games. This caused a lot of friction and he was mortified to the point he wouldn't invite and friends around.
DS2 is 13. He has ASD. He doesn't really socialise although does (with friends) over games on his laptop.
For Christmas I got him a (secondhand) Xbox One (he asked for one) and a TV for his room to play on.
He doesn't play on it at all because he only has one game and his mates all play 18 games.
I am adamant he is not playing GTA. But I know he plays 18s at his dad's and I know his brother has bribed him a fiver to not tell me he's played 18 games on his (DS1) PS4.
I wish everyone stuck to the rules (re this) but they don't and I feel like I am fighting a losing battle and am digging my heels in pointlessly and have paid for a gift that isn't being used.
AIBU or do I give up and relax my rules?
