This sounds like an old wives' tale I know, but I had an appointment with a midwife yesterday and during a discussion about natural births she happened to ask me what my shoe size was. When I said '4', she went "ooh". When I asked her how that was relevant, she said that small shoe size can be related to the size of your pelvic bone, making a natural/vaginal delivery more difficult. Has anyone else heard this before? Can it possibly be true?
