Hi Reddit! 

My little brother is mature for his ag. Entering Sophomore year at the end of the summer. I live with my boyfriend and I am currently pursuing my Masters in Education while my bf works full time as an accountant.

My little brother is staying with us and I am wondering if it is okay to let him have a few beers while my boyfriend and I do. It's 4th of July and we'll be keeping a close eye and hanging out with him all weekend/week while he's here.

He stayed with us last year too and we let him have some beers and everything was okay, I just wanted to get some outside perspective to make sure we are not negatively impacting him in any way. I want him to have a healthy relationship with alcohol and be responsible and want to make sure letting him have a few beers under my supervision won't be counter intuitive. Thank you!
