First DC 2nd degree tear, stitches and it was bloody painful for weeks later. Couldn't walk properly afterwards, and couldn't understand the people who could. Also thought I'd never be able to wee without pain again.
Second DC, no tear just a graze. Was walking fine, no pain when I went to the loo. It was amazing the difference in the way I felt.
Second DC was 12 and a 1/2oz smaller, and was a much quicker labour and without me really having to push iyswim. The placenta took more effort to get out than DD First was a long labour and a long second stage and I wasn't very good at pushing I think.
