Congratulations!! The piece of advice I wish someone told me is the first while sucks but it’s temporary, and during that period the kid is going to be constantly learning. They’re learning off of you, your partner, and the world, but mostly you as the parent. During this time, the kid will be doing nothing and might upset you with all the crying and what not. It is super important that you model the person you want your child to be. That means showing calm in the face of exhaustion and being yelled out by a tiny bundle of pee and poop (sometimes puke). Always calm, take deep breaths. Make sure that tiny thing knows you are there and you are unfazed. Model the person you want your child to be in this world.

Besides that, enjoy the ride. Hardest and funnest thing you will do!
