Pre-dads and dads who can't nap?

Wife is 39wks and 1 day. Weird question for dads and PreDads out there. Obviously sleep deprivation is real in the newborn phase and beyond. This has me a little nervous for my own sanity because I've never been able to nap myself. No matter what, if it's daytime, I can't sleep.

Anyone have this experience or any strategies to scrape up the extra Zs when in the trenches?
