Our ds2 for last 2 month is a complete nightmare. Would scream in the middle of the road if he doesn't get his way, would hit me. We have time out at home and reward chart too. He starts reception in sept and can not wait. I read somewhere that at 4 there is a high dose of hormone released into their system and that can drive them mad for a while??? Have 3 ds, he is in the middle. Very creative, nursery has no problem with him. Why me????
