Puppies - all the best with your upcoming birth. I think as long as you are aware of the risks involved with elective c/sections as opposed to vaginal births and you sound like you have really educated yourself, then you are doing the right thing by you and your child and noone can argue that.
Just keep in mind, that like vaginal births, c/sections (elective or emergency) can be just as traumatic for a newborn. Birth in general CAN be traumatic for babies.

I wish you all the very best with it all hun. I truly think you are very brave opting for a c/section actually!!! I would rather avoid it!
