Mr W will throw tantrums. Sometimes he is hungry or tired and when he gets to eat or sleep, he is fine. Sometimes he does not get his way and that is when we explain things to him then ignore him - he stops after a while.

We also had a babysitter who came to our house and she was too doting on him, and he was using crying/tantrums to get his way, so we moved him to a school, for this reason among others. ( We saw a big change in his behavior when she was gone for a week and he had to share attention with other kids. )
