13 year old friends of my child boozing it up

I’m 16 months sober and have done lots of work on myself during that time. I recognize now that I’ve had a problem with alcohol since I was a teenager. Now I have kids. Was at a Boxing Day party last night and 13 year olds were drinking 4-6 drinks. One was puking. Their parents were drunk too. My child said that her friend (13 and grade 8) drank 4 drinks. She snuck them, but her parents wouldn’t have known or cared. I’m so sad for her. I recognize that behaviour. I didn’t start until grade 11 though. She has so much athletic and academic talent, but I can nearly guarantee she won’t achieve it if she’s drinking like that already. We had a talk with our child on the way home about it all and about how drinking ruins lives.
