I was talking to a pregnant friend today, and she was saying her midwife says that a baby's heart beat sounds either like horses' hoofbeats, or a train. And if it's one it is a girl, and the other a boy...she couldn't remember which is supposed to be which!
So which does yours sound like, and do you know whether you are having a boy or girl?
Mine sounds like a train, and I don't know the sex.
