As I had been steadily losing my voice* for the past few weeks due to the constant repetition of key phrases and the high volume in which I have to yell to make myself heard, Paul has made me a couple of handy recordings. This is my favorite one. (The other so far is "Please clear the table." I'm also hoping for the combo "Go try a pee and put on your pajamas".) Please feel free to download it and use it in your house. The secret is to loop it so that they HAVE to go try a pee to so that you will make it stop.
*voice is getting better, thanks
