Congratulations!
I don't know how it is for other men but I remember having not a fucking clue about anything children related.
All I knew were movies, 9 months, pop, hey presto, yay! -- I had to do life to figure out the significant trauma that pregnancy can bestow on couples.
The one my wife carried to term wasn't easy -- and by god did she give it her all. At one point we nearly lost them both.
Yet it was thanks to some quick work of doctors both were able to survive and we have an amazing life now.
100 years ago I'd have been single again.
Men, we're never prepared until it happens lol. Kudos to your husband for braving it like a knight in shining armour :)
