Tips for an Interviewing Mother

I just found out I am scheduled for an interview tomorrow with a company called Boundless Network for some potential marketing contract work. In light of that, I have put together a check list of things for me to remember as I prepare for the interview:

1) Find an outfit to wear that does not have spit up stains.
2) Find an outfit that does not consist of running shorts and a tank top or pajamas.
3) Shower.
4) Use a real purse, not a diaper bag.
5) Try not to talk in a voice that is 3 octives higher than your normal pitch.
6) Remember to shake hands, not play patty cake.
7) Don't seek out the "family" bathroom at the office.
8) Don't ask the interviewer if he's "doing a poopy".

Any other tips?
