Netty, if you want I can go into detail about bone density, but it's fantastic that they need to re-do the scan as it shows your baby is really strong and healthy. I know it's a bit of a worry right now, but it honestly is a good thing that they have to re-do the scan. I'm not sure exactly what they're looking for, but I'm sure it will all be OK and you may be sent for someone to turn the baby, but breech isn't a serious problem (well, OK it is now, but it's not disability-causing or anything like that).
