My just18 year old has a few beers with me & his stepdad at weekends, but we don't drink during the week. He's quite quiet and lacks confidence and I definitely notice he's more relaxed and chatty after a beer or 2. However he has started having weekly zoom meetings with his mates (which I think is great - he's one of the poor upper sixth lot who've lost their last term at school, A levels etc) he has the zoom chats in his room and for the last 2 meetings he's had 4 cans of beer. I think that's quite a lot to drink when you're on your own and said so gently, but he argued that he wasn't on his own. I wouldn't worry if he had 4 beers at a party but this feels different. I had a sleepless night worrying that he is beginning to use alcohol as a prop, his Dad is a heavy drinker so there's some history there. Or should I relax let him get on with it?
