Our Toddler (19 Months) Is Sometimes Totally Out Of Control.

Our toddler (19 months) is sometimes totally out of control. He throws himself back an forward, bites, hits and screams. It takes allot to calm him down. He does it for no good reason. I don't think its the normal temper tantrum its much more sever. He's a danger to himself and others. Imhis grandmother and had 5 children and 15 grandchildren and have never seen this before. Is this some kind and of illness.
