Choosing a birthday

We went along to my consultant appointment anticipating a conversation about booking an elective caesarian section for around 37 weeks.
Twin 1 is currently transverse, and if that situation continues then there really isn't any option. A planned c- section is without doubt the best way to bring them into the world in that situation.
We weren't expecting to simply be asked "well after next week [35 weeks] when do you want to have them?"

The problem you see is that my last 2 labours were what they call "extreme precipitate" once things got moving properly the babies were in a hurry and arrived in under 2 hours.

So if my waters break or I start to go into labour, with twin one transverse then they are going to have to move very quickly to avoid cord prolapse etc.

Thing is, if it happens at night then realistically it's going to take an hour to an hour and a half to get me into theatre, by the time they've assembled teams etc.
So we're left with a near impossible risk calculation to do.
We're weighing up the dangers to the twins of being born early but in a controlled situation.
Against the benefits of reaching full term, but risking a passage perilous into the outside world.
And somehow we have to decide what's best.

My previous pregnancies having all reached 41 weeks (or almost) is reassuring, but equally my body decided it was time to evict each of those three as their weight hit the 7lb 13 mark, and the combined weight of the twins is considerably higher than that already.

Anyway, they can't come yet, the house is a mess!
