Outburst controlled

Well Hannah had a outburst this weekend while her mother was in Washington DC. I noticed if I nipped it in the bud ASAP and not let her rant and rave like a crazy girl I am able to control her emotions.

Scenario:
She is standing on her bed yelling at her sister turning red and just screaming.
So I run in see this and "Calmly" say OK I am here you need to sit down and talk to me like a gig girl and not scream like a baby. I am here to deal with Lila (her annoying little sister, as she calls her) if she is being naughty.
So she immediately sat down we calmly talked and the rest of the day went on.
What did I learn, calm rational conversation and the world moves on!
