"Nanny, after DS finishes eating, please clean his hands and face, and wipe any food he got on his clothes." "Nanny, before DD pulls out a second toy please encourage and help her to clean up the first toy she'd been playing with. Before she leaves a room please encourage and help her to clean up in there."
TELL her what you want.
If you are dead set on firing her, it sounds like she hasn't been with you long, so no need for two weeks pay.
You fire at the end of the day, so the person doesn't have to work while they're trying to process their feelings. End of week if possible (so on a Friday afternoon, rather than a Monday morning). When you fire them you hand them a check for all time you owe. You say, "Larla, Greg and I have decided to let you go, due to the fact that you didn't follow through on your verbal agreement to do housework despite numerous hints I gave you. Here is your check for all your hours worked through today. May I have your key to our house? (Then you make her give it to you right then.) Thank you so much for all you've done. Best of luck to you in the future."
Those are the things you say to a 14 yr old mothers helper, not a nanny with experience. Assuming the nanny isn't 14 and has experience she should definitely know these are things you do as a nanny. When you hire an experienced employee you do so under the premise that they already know how to do the basic requirements of the job, anything above that is up for discussion.
