Fast forward 10 years and to more specifically two days ago. SD15 hasn't outgrown her tantrums because they still work for her. Where most of us would walk away from a tantrum her dad first objects to it even happening, then pleads with her to stop,  gets really angry, and eventually gives in. 

I had a startling surprise yesterday when I was checking over our security camera footage and deleting files. (Note: We have crazy neighbors who like to shoot at us and vandalize our property because I called the sheriff for a welfare check on their house after a 1 1/2 year old had been locked out of the house. The kids inside left to babysit the small toddler said she was just fine in the backyard as long as she wasn't hurt and she was being potty trained. So we have cameras up now.) My startling surprise when I played one of the saved files from the camera was the sound of the back sliding glass door being thrown open followed by the loud demanding voice of SD15. I so wish I could play the recording for others to hear. 

DH thinks her behavior is because she's frustrated about something, misses her mother, is upset at her mother, feels pressure from school work, had a bad day at school, having problems with some of her friends, PMS, learned it from her mother, or it's just a phase all teenage girls go through. I want to practically scream in his face. None of this is new! She's been acting this way since I met her when she was 5 years old. It's still the same behavior she has always had. It's just not cute anymore!

Looking on the positive side, at least he acknowledges that she's been displaying poor behavior. It's a step in the right direction I suppose.
