I have given birth in France twice.
Yes, the procedure is likely to be extremely medicalised, but then again for a pre-34 week baby I would guess it would be anywhere.
One thing to bear in mind is that many obs still give routine episiotomies in France (particularly when women have an epidural, which is, indeed, the only pain relief offered), so if you do not want that watch out for it and make it very, very clear (you may need someone with you who not only speaks French, but is very able to stand their ground for you).
Buttonmoon, I am afraid I agree with Mycat re bfing - the support for bfing is a shambles and most women I have met here were told they 'couldn't' bf (I was too, but I ignored them). If you have a preemie and you wish to bf you may well have a fight in your hands.
OTOH, I can vouch that frequency and strength of bh have no relevance on imminence of labour - I was fairly convinced from the bh I was having at 34 weeks that ds2 would be early, in fact he made it all the way to 40 weeks! So I wouldn't be too panicked about having to deliver while on holiday....
