well, I would respond but you already know what I think. I *love* my Mother's Helper.
And I agree with Tamara that it is important to stress the need for flexibility. That was something we said right off the bat when interviewing: we need someone to help with cleaning, office work, kid duties, ect and I will be home the whole time you are working so you must be comfortable working around me.
I hope your Saturday cleaning is over before you know it!
Go for it!...
