I know its all been said before but I need help with my 21/2 yr old ds, some days he's great, some days he's ok, some days like today he is a complete demon. I have left him watching cbeebies as I cannot physically cope with being in the same room with him. since waking up this morning he has: bitten me (on the breast-copying the baby!), weeed all over the house, deliberately not accidentally, thrown his cereal around, bitten the baby, stood on the baby, thrown all the bathwater out of the bath, thrown all the washing around as i tried to put it away, rubbed cream cheese into the carpet, eaten half a tube of toothpaste, ripped his favourite book and just now has grabbed my necklace and deliberately pulled it so hard it broke. i am at breaking point. have screamed/ done timeout, played with him/ tried emphasising positive behaviour (not easy) after screaming failed i am now trying to remain calm- failing dismally. oh blimey, he is now trying to bf baby godlovehim!! please has anyone got any coping strategies- don't say don't write on internet forums instead of playing with him-i only normally do this at night or when he is napping
