2 year old is still in that 'I can say a few words but not speak properly' stage so in frustration hes screams the most blood curdling scream, its horrendous my and dh get so angry about it, as its relentless and sometimes I could just walk out when ive had a particularly bad day, he also had horrendous paddies flinging himself if ive picked him up to remove him, biting,nipping throwing himself at the slightest thing, throwing things...when hes becoming too aggressive I have to put him in 'lock down' to sit him on my knee one hand across his arms and one across his head and count to 10 so he cant hurt himself or me any more, I shouldn't have to do that though 
ive made allowances as hes had a lit of upheaval, had to move 4 times in a year last year, but Im gonna end up in an early grave at this rate, I already have another child to deal with, if anyone has any advice on better ways to calm him down would be much appreciated.
