Self-professed nerd dad here. I loved this when I was dealing with the panic of an infant. It's fun and contains some useful info too.
The Baby Owner's Manual: Operating Instructions, Trouble-Shooting Tips, and Advice on First-Year Maintenance https://toptalkedbooks.com/amzn/1594745978
The Baby Owner's Manual is an actual thing with real advice.
Pick up a book or two to fill you in on the basics. My husband really got a lot out of these two:
This one for the nuts & bolts mechanics: https://toptalkedbooks.com/amzn/1594745978
And this one for more the emotional/what to expect: https://toptalkedbooks.com/amzn/0399166262
I was also a fan of the pregnancy app from "What to Expect when You're Expecting" because it gave week by week updates about what was happening with Baby and tips to deal with the physical and psychological changes.
Then start talking about what you want things to look like. If you're wanting to get married before Baby arrives, sooner is better because you're going to have a lot more on your plate coming up very soon.
Scheduling an appointment with a doctor to find out how far along, etc. will also give you an opportunity to ask questions from someone who will be with you every step of the way.
This is one of my favorites. Fun to read and useful, non judgmental information.
I got my husband his favourite candy (a tub of Costco sour keys), a funny dad-to-be card and the Baby Owner's Manual because I couldn't remember what my original plan was (yay baby brain?). /r/predaddit seems to love this book and my husband is already getting a kick out of it. I just remembered now that I see this post that I meant to get him this Mercer Mayer book . We celebrated father's day with my family last weekend cause we all have a wedding this weekend...maybe I'll surprise him with it after the birth. Thanks for the reminder!
My husband really liked this one. It's not specifically for dads but it's funny and written in that matter of fact way that he likes.
