I had babies at 22 and 24- all fine, no complications, easy delivery with no gas and air, no stitches, recovered well enough. My body looks a mess (stomach muscle seperation, loose skin, saggy boobs and stretch marks to my ribs) but not had any real incontenence issues or anything like that, so very lucky.
I'm now incredibly worried about doing it again in my thirties. It feels a lifetime ago and I feel comparatively very old. Will it be much tougher? Am I going to need loads of intervention? Is a third degree tear and incontinence for life basically a given? I must admit that the many pro elective C-section posts on MN are influencing me a little.
