my bubz was posterior at my 32 week check up also, i naturally freaked out and the midwife seemed worried that labour wouldnt be as easy as it could be for a first time mummy.
since then ive been bouncing on the swiss ball every day, walking (even just a 15minute walk helps), and sitting sideways on the couch with my feet on the floor so im constantly leaning forward.
had another midwife appointment yesterday and bubs has turned half the way he needs to before he'll be completely anterior, so obviously what i've been doing is helping alot!
a friends mum is a nurse and she recommended getting down on my hands and knees and swaying back and forward.
hopefully some of these help, for both of us hehe!
i've heard forceps are used with most if not all posterior births, so get down on your hands and knees hehe
