Don't let yourself get too stressed out by it all, hon. I'm sure if she's bringing the kids and is at all professional she'll have it all under control. Do you know the age of the kids? There's a good chance if they're in school they'll understand that they have to be quiet (and might just sit there playing their Nintendo DS or something). I'm sure if you called the midwifery program and asked for a contact you could call her just to talk to her and put your mind at ease.
