I have a private midwife looking after me. I went for a check up during the week and she listened to the baby's heartbeat. We had a chat about it and then she told me that they have a theory that if it's a boy, the heart rate is between 120 - 140. A girl has a much faster heart beat between 140 - 160. Wonder if anyone else knows anything about this? I'm happy to keep on guessing. Only want to know when the final push is over!!!
