My youngest son looks up to his brother so much. I'm terrified that he'll turn out just like him. How can I keep him away? My fear is that trying to keep them separated will backfire – where they team up against me or hang out in secret. What's the best way to tell him about his brother without devastating him or causing him to act out? I don't know what I would do with both boys being addicts. I want to be proactive.
