I have my 20 week US tomorrow and will have to bring my 11 month old with me. My husband is a surgical resident who works 14 hour days Sunday through Friday so there is no day he could watch our daughter. We have no family who lives here to help. Have any of you had to bring a young child to your 20 week US? If yes, how did it go? Recommendations?

Update:

Yes, children are allowed. No, I have no one to come sit with my daughter at the doctors office.
