He's always been a homebody, never really been out much till this summer, now he has got in with some boys at school who go to the park on friday nights and drink - I don't know where the drink comes from but need advice please on how to make him see this is going nowhere behaviour - never had much problem with him before so struggling with how to discipline him. I only found out about the drinking after the first fighting incident and he said he wouldn't do it again. He denies it but I know he is still doing it. I suppose I could stop him going out but he does only go out once a week, till 9.30 and I collect him. His school work is good and otherwise no problems - how do I nip this in the bud?
