Sorry It was a bit of a juggle for me last time; ODD wasn't old enough to be in school so I had to make sure DH was able to watch her. She was at that "squirmy" age still. ehh, I got to be "friends" with the NST nurse. We chatted a lot and she had me talk with the nervous moms - the ones who came in later in pregnancy and such. Since I'd been doing it for so long, I offered support/whatever if they were nervous. And sometimes they asked me questions instead of the nurse - I had to be careful to explain I wasn't a nurse, but IME XYZ type of thing.
Maybe they won't have you go in for NSTs so early/often. Every doctor is very different (as I'm finding out now with my new doc)
