Congrats! Reddit sucks but /r/daddit has a wealth of knowledge and a supportive user base.

So.. for me this is what I did beforehand.

Bought a rechargeable fan that'll hook onto the bedframe at the hospital.

Bought her some cooling packs for her nether regions. Post birth needs a bunch of stuff. Sits bath items, Hemorrhoid wipes / cream. Etc

I bought my own dad bag. So we both were prepared. I kept a change of clothes for all of us in each car

I bought cloth diapers to be used as burp cloths. Buy a lot of them. And don't buy the expensive burp cloths. https://a.co/d/apyEjCv is what I bought.

Additionally they make great rags later. I'm into cast iron and I use them for seasoning rags.

Packing cubes the small ones keep stuff together. I keep desitin diapers and powder in the same container for ease of access. https://a.co/d/4qOrfgW for example

Bought these for powder on the go. https://a.co/d/i1zunEZ Because powder containers are huge.

It's difficult and sucks quite often. but it's so rewarding. One of the manliest things I've ever done was feed my newborn moms milk at 230am while she was sleeping.

Good luck op!

Edit: feel free to dm me if you'd like

Also Go out to eat now. Go to the movies. Watch a TV show. Sit in silence.. Be out and about with friends.

It get a lot more difficult after the kiddo.
