I'm actually quite a level headed person and don't find DS particularly "emotional" and i do have a disliking for over dramatic people, but maybe I'm just used to him.
From some of the posts on here, i've never had to leave him in his room to just calm down. Usually I just talk it through with him, although I probably am a big softie.
Most of his tantrums happen when I turn the tv off but he gets over it within minutes.
Surely 3 year olds are allowed 1 - 2 tantrums a day.
