Both babies were 4+ kg.

I laboured in water both times.
First one I only pushed as my body urged, and only grazed. Second stage was 2 hr 27 minutes.
Second I asked for coaching, but if it was offered, I didn't even notice. Again I pushed as my body urged, ended up with 2nd degree tear and a graze, second stage was 10 minutes. But second time round it healed a lot faster, I just spent more time lying down afterwards. That made a big difference.
