If you can get her to use it, try a pair of FRS radios. Instead of yelling, she just has to press the button and talk. And the person on the other end doesn't have to yell back, or run. If she gets a quick response, she might be less likely to yell.
Just a thought. You could give the other unit to whoever has Nana-watch. But it might cut down yelling, and running around.
That's a good idea. But our house isn't really that big. She was standing at the top of the stairs and could have spoken my name in a normal tone of voice. I would've responded.
I mean, fercryinoutloud, I'm the one that hears Luke crying over the TV, the DVD I'm watching on the computer, the dishwasher and Jr....
But she yelled the whole explanation from the top of the stairs. It's a behavior thing.
I'm pretty adamant that she has GOT to learn how to live in our house.
