My son will be 4 next month. As an infant he was very mellow, hardly cried. As he gets older his behavior deteriorated dramatically. He is the youngest of 5 and the others always were good to him. When he was 2 he started getting naughty, which I owned up to the "Terrible Two's". In the past months, especially this last one, he started throwing severe temper tantrums, even breaking his toe. He SCREAMS over everything! He will hit, bite, pull hair, anything that he can do to hurt someone. He often asks if people are dead. It is at the point where his siblings don't want to be around him and my family is STRESSED OUT! He doesn't play with his toys anymore, he rarely laughs or even smiles. He can be such a sweet and loving kid and it is so hard to see him when he starts flipping out. But when he does flip out its nasty. We cant touch him then because he will scream that we are hurting him and if he thinks we are physically restraining him he REALLY goes berserk!. Any advise? My family seems to be crumbling because of his antics.
