I have noticed on another forum I use that quite a lot of Mum's are being given sweeps any time from 37 weeks onwards or being told by their midwwives to 'have lots of sex to try and encourage baby out'...
My youngest child is 6 and this just didn't happen when I had my children. You would only be likely to get a sweep if you were very overdue, and certainly not at 37 weeks. Why are the health profession so keen to get babies out?!
