Ds was kicking and punching like mad during my last day of contractions, he punched and broke my waters. No idea what he was doing after that it was so fast.

I was in early stages of labour with him and for a couple of weeks (and possibly dd1), so I had a lot of monitoring, they were both calm during the contractions.

Dd1 was distressed in the end as she was stuck.

I think they know what to do and when everything is right they just chill and get down to business.
