A zillion years ago I worked Maternity, OB/Del we had a 16 yo who came in ready to pop. She lived at home with her parents who didn't find out she was preggers 'til she went into labor. I'd just had a baby myself and I had to know how she hid it, it had been my experience after a certain point there were things I just couldn't have kept hidden if I wanted to. Anyway she told me she wore sweat pants and zipped sweat shirts all the time and she kept her hands in her pockets when her parents were around. She was fairly small and had a 7lb baby. Boggled my mind!
