DD was still swapping between head up and head down until 36 weeks, each weekly appointment she was a different way. My ob said she didn't pay too closer attention to which way around they were until 36-37 weeks, I mean it was checked and recorded at each appointment but nothing done or said about it.
I'm 29 weeks now and I think I can feel the feet down low, so I am in a similar boat. I think the baby is also posterior at the moment (just a hunch) so I'm not really winning any awards for ideal baby positioning!
