Ok, so I would just like some clarification of the term "engaged" - but first here's my story...

I have a friend who is 40+1wks and has been told that the baby's head hasn't engaged at all (that is, bub is still free floating) and that means she is likely to need a caesar. (By the way, this is at a hospital where 4 of my other friends have been told the same thing - and ended up with C sections)

Now I know that it's quite common for babies heads to not engage till labour, (that happened to me with DD!) but does that mean that a baby can still be free floating then engage or does it have to be settled into the pelvis somewhat before properly "engaging"?!

Please wise ones, shed some light on this for me!!!
Thanks
