All i can say to MusclarTeeth and DarkMellie is good god damned luck. I wish your partners the best, hope for a swift and relatively painless delivery... mine had it rough. Previous motorbike accident stuffed her hips but she pulled through, even though the docs said it would most likely be c-section. She's well, well sore today, can barely walk.
A few notes to take from the experience.
It will be hard. It will b painful to see your other half in the worst pain in her life, but the end reward is so beautiful that it all disappears when you see that little face looking back at you. The miracle of birth really is just that, and I had my head down there for the most part... didn't make me think any differently and I was actually quite thankful I did so. Being able to see her little head coming through meant I could see her first moments in this world.
Wouldn't swap what has happened for any money in the world.
Again i say, good luck!
