kml - as always - raises a good point. I recall with B's GS3 that he would also be very attention seeking and get quite wound up and aggressive. What worked with him was making him the centre of attention for a while, usually holding him on my lap and rubbing his back (something B taught me). Yelling or other disciplinary measures were counter productive.
B's opinion was that he was acting out because he had had so little stability in his life and was so used to people being temporary that he acted the way he did as a result. Over the months he certainly calmed down a lot and I recall in the last few times I spent time with him he would ask me out of the blue quite regularly if I loved him. Not being able to prove to him that people do care and do stick around is certainly one of my bigger regrets on that relationship ending.
