My son and his partner are in their early thirties, and expecting their first baby. When they visited the midwife last Friday, she said she couldn't tell the position of the baby because there is too much fluid. She is 29 weeks. The midwife asked if all the diagnostic tests (sorry, I don't know what they are) had been normal (they had) and left it at that. Its been so long since I had a baby, I don't remember if this is something to worry about, but I'm doing it anyway ...
