Oh congrats ovr! I'm so happy to hear this. I'd suggest purchasing and reading Babyproofing Your Marriage: How to Laugh More and Argue Less. I wasn't exactly able to use it as I had D18 very young and my exH was a dumpster fire of a human, but my happily married friends who did things in the "right" order swear by it. I also strongly, strongly suggest you buy W What to Expect When Your Expecting and absolutely do not let her near the internet unless it's the website that goes along with that book. The internet is a rabbit hole of anxiety inducing medical anomalies that will send her and probably you down a dark well of worry that isn't good for anybody especially baby.
Parenthood is one of the hardest and most rewarding things I've ever done in my life.
