The answer

- 20-minute naps are arguably too short for a restorative nap

- 30 minutes a time would be better, but 90 minutes allows a full sleep cycle

Interestingly, newborn babies are on a 90 minute schedule. So are the parents...

Though to be fair, that only lasts a few months until it's 2x90 min, 3x90 min, etc.

I haven't ever heard a parent say they felt like Superman on that schedule, though.

Most parents gets the bad side (waking up at night) without the good side (napping during the day), though.

I really loved the weekends when my son was younger and would still have an afternoon nap and we ended up napping at the same time.... But I did certainly not enjoy when he was a baby and woke up around 4:30am full of energy and I had to offload his mom and keep him busy until it was time for me to get ready for work just as he decided it was nap-time again.

If I got to go down for a nap again whenever he did I think I could have quite enjoyed it. Unfortunately I doubt work would have agreed.
