D.H.
Tell her mommy would like her to go with her to work, but she has to be potty trained first......put it in words she will understand.........that she has to be a really big girl..........then go over the DVD again.....and keep a good eye on her......
If it doesn't work, she's not ready.....hire a baby sitter, but consistent with training at home, sitter and where ever......put great effort in this and in no time, she'll be on board....
Hang in there....and congrats on the job...
