Sooo that's what it's called!!
I have one of those 2. I have one that was tired today...very sensitive. When he throws a tantrum I walk him back to the back bedroom and tell him he can scream, cry what ever he wants but when he feels like he's better and is done crying he may come out. There is no eye contact when he is doing it and I walk away to a diff. part of the house. He will normally stop and make the decision on his own to stop and come out. He is 2 1/2. I love it!!
