sounds like he could be dabbling with cannabis, stealing needs a hard line, I let my son get away with stealing from me because I didn’t want to criminalise him (he was a bit older) I should have had him arrested looking back maybe I wouldn’t be going through what I am now if I had.
Who says your son has an attachment disorder, if he was a baby when he came to you, he should have attached to you, an attachment disorder can be rectified and I am sure the love you have shown him over the years will have done that. Don’t let him hear that please. It is easy to blame his birth parents and early start in life but sometimes it is just that kids are experimenting, he is 15 after all and there is a lot of peer pressure. Keep loving him, tell him often and be strong. xxx
