Sounds like impending pox, Titsa. What a pain.
Fluffeh, I have a friend ready to take my two who works from home and is ready at a moment's notice. She took DD last time round. I'm planning a home birth so the middle of the night isn't an issue for me, but I'm sure as a one off and exciting occasion you could wake your sister. Ask her what she'd rather you did.
plinky also unable to see but jealous. My hospital does 32/36 week scans but by then you can only see individual limbs and things!
