There’s a lot of great advice here, but the most important piece of I ever got as an expecting parent was “Your baby isn’t my baby” Keep in mind that most pieces of advise you get are probably helpful but they might not apply to you and partner and your new kid.

But for me the second best was to see if your wife can express some bottles of milk so that you can do some feedings. Breast milk is great but it doesn’t need to be fresh from the tap. If you’ve got a few bottles in the fridge you can take over a feed and let her sleep. It’s also great for you bonding with you kid.
