Just wondered what everyone else does. When they have those crazy, about nothing, kicking & screaming tantrums.. I don't mean 'normal' tantrums - I mean the mammoth ones. My ds has between 1-4 of these a day..& usually I start off calm but after about 10 mins of getting nowhere & escalating screaming, I lose it & resort to threats to smack & on bad days hands up I smack out of utter desperation to get thru to him.. After a warning & very controlled on back of legs.. But I know it's not right.. In fact by that stage it's all absolutely pointless as he can't see or hear me for screaming.. I can't walk away as he throws things around & is a danger to himself.. So what techniques do others use that work?
