My 12 year old son has had 22 detentions and 2 suspensions in the last 27 school days. I brought him to live with me recently after he started getting into trouble as previously this has made a big difference, and he goes to bed on time and school on time when living with me, which he often does not do at his mothers. Today he decided that he wanted to go back to living primarily at his mothers as she "does not care as much". Previous to living with me recently, in his mothers care he has tried drinking, smoking, vaping and smoking weed. I do not know what to do, and am disaster thinking. He came close to getting suspended again last week, and we have been told that he is close to getting expelled.
