My problem started when my daughter was only 6. I didn't do anything to get into trouble but I set such a bad example. I normalized having to have a drink in your hand for any leisure activity. Our kids model our behaviour. She got caught drinking when she was 15 and I blew it off but then at 16 she got caught again at a school dance. That was my wake up call. I stopped and set a better example. She's 26 now and not a drinker. The girl she got caught drinking with is in serious trouble now. You are still his father, he will still model your behavior. There is still time to change the road he is on and save him this. Absolute and complete accountability about how your drinking affected your life and his.
