Gee, this is hard to think of...
* Maybe some questions about when certain milestones are due (on average)
ie First tooth, step, smile, recognition of mummy and daddy?
* Questions about medical terms, birth and baby?
* Immunisations due?
* Number of bones in a newborn?
* What is the most common eye colour in newborns...(apparently blue then it changes ?)
* How strong is a newborns grip? (able to carry own weight - read in a preg book)
* At what age can your unborn baby identify sounds etc in womb?

Wow, that was tough...I'll keep thinking of more. Have you tried reading through a preggo book or two?
Good luck and hope I helped
