I thought mine had turned at my 27w appt yesterday, but I was wrong!
My midwife said that she doesn't mind where they are until about 33w or so where the room starts running out. So I guess it will be interesting to see if I have a turned child next time.
Jenna turned at about 30w from memory. I didn't even notice even though I had been feeling her bum (I thought it was a head..... duh).
