To be quite honest with you unless there is a specific question in mind, most every thing you could ask could be found in a good book or online. I would tell her to invest in a good book. Not to say there is nothing you can ask, but in a normal healthy pregnancy questions like diet, things like that are in books. Also with my first the nurse came in and went over everything so I didn't even have to ask. If she has a concern ask about it, or if she wants to get a feel of the practice then ask about how they run their office.I don't think she needs to brainstorm for questions though. Congrats to her!
She is feeling very nervous and I understand her desire to look for questions from various sources. Thank you for your input!
