Do you think you want a c-section? Try not to base your outcome it on your sisters experience. I'm not trying to be patronising, I know you know what you're doing, it's just when you've had someone close to you have a similar experience it's easy to get you thinking yours will be the same.
Don't forget Lou and I both had back to back babies who got stuck, and although my birth was far from ideal, I'm still glad I didn't have a section (just my thing though, I would never want a section personally but nothing against them!)
Honestly if you want a section and think it's the best thing then you just have to ask, make an appointment and tell them you can't cope.
My only concern is that you will regret it afterwards, because you really enjoyed your first birth, and have been really excited about doing it again. And if you choose to have a section now you might kick yourself later and wonder what would have happened.
I hope that makes sense? Just consider everything and if you think a section is the way to go and phil can support you enough afterwards then just ask for it and see what they say.
I hope I'm not coming accross badly, I'm trying to help
