I had 12 weeks of paternity leave at my last job. The only rule was that, as secondary caregiver, I couldn’t take it all at once.

I spread out the last 8 weeks and took every other Friday off for several months. It was awesome, and if it reduced my productivity, the difference was imperceptible. I had to be a little more keyed in on Mondays, sure, but I always felt more than capable after a long weekend.
