my boys didnt turn until last moments, but i am only 5ft 2 my boys were almost 8 and 9 lb and extra fluid! so my DS 2 used to flip forwards when i was 30 odd weeks along wasnt the most pleasent experiance lol and more than occasion. my first tried turning when i was in labour but ended up transverse and stuck behind my pancreas! (or how you spell it lol). my sister also had c section from breech bub she was breech then turnt stayed head first until labour and decided to change her mind! her bub was only just over 6 lb's! it doesnt matter what size cause they can turn themselves its just if their happy being stubborn lol.
i cant have a natural birth, (lots of problems! thank god i didnt try delievering naturally! they didnt know until a d&c!) but i really hope she turns for you! xxx
