I have posted about ds2 already but would like to know what people make of his behaviour bearing in mind that he has not been diagnosed with anything as yet.
trying to discipline him or talk sternly about what he has done or give him a consequence is a nightmare . he is 12 years old. for example :
ds2 has been asking for a facebook account , for various reasons i said not yet. on Thursday night i discover he has set one up and added friends of mine asking them to please not tell mum 
so, i told him i was very annoyed , that it was really out of order and sneaky etc etc
i didnt shout or anything,( told him there would be a consequence but hadnt decided it yet ) but he immediately became REALLY irate.
he was so cheeky that the initial crime seemed to pale in comparison really.
he screamed on and on how i wreck his life , he hates me etc and then as it was bedtime he spent 3 hours banging and shouting from the bedroom. when i went up he would have his fists clenched and be extremely angry .
Next morning his mood was barely any better (not helped that he had pain in his jaw and we had to go to the doctors) but he was still going on, just wouldnt stop . The things he was saying to me i have never tolerated and i was aghast.
he refused to go into school and paced around the house , picking plant pots up etc, wanting to throw them but managing not to.
now, i was saying stuff back to him at times , it was nigh on impossible not to. he was saying he didnt care , i would say you should care etc
i did walk away at one point but was then worried about all the banging i could hear.
sometimes it changed to being upset , saying that he hates himself etc
eventually he calmed down.
tbh i am reluctant to dish out consquences for bad behaviour since he has got like this and i have never been a pushover but i cant hack the repercussions.
