The Tantrums occur when she doesn't get to go where she wants or she perceives that she is being left behind or something. And I mean that if she things were going into the next room without her type of thing, not the where going to day car thing. Oddly enough she loves the day care thing and doesn't even pay any attention to use leaving here there.
We ignore her. That's what all the Therapy people tell us to do and I'm pretty good at it.
With outburst we just try and use soothing tones and redirect her attention. That or lock in a her toy chest.
