Oooooh. Sorry. Does a smack on the butt get her attention? (not for the baby of course). On the bright side, enjoy the "fun" part of cleaning while you can and try to make a game of it, sometimes life is easier that way.
Another part of the punishment for my six year old (and maybe it's the most effective part) is that until she completes her punishment she gets the cold shoulder from Daddy. That may or may not work for your three year old, but it's worth a try.
