Hey congrats! Kids are amazing. My little boy is about a year old so my advice is this:
1. It gets better. The first few weeks/months are really hard. It's ok for them to suck. Don't buy into the whole "kids are amazing everything is amazing" mentality if it's not how you feel. My son really started getting fun around 6 months. Also post partum depression sucks so watch out for it in both of you (yes, guys can be effected too).
2. You have a choice now. You can choose to replicate a lot of what your parents did or you can choose to not. Ask you spouse what her instincts are and compare them to your own. Critically think about whether or not it's something you want to do and why. I know for me I am avoiding a lot of how my parents raised me. I don't agree with how they did it and that's ok.
3. Be careful of new child raising theories. Many of my friends with kids subscribe to "new" ways of thinking about feeding and sleep and whatnot and their kids are annoying and their lives are chaos. My wife and I are following kind of old fashioned thinking and our kid is smart, fun, and just better than everyone else (though I may be a bit biased). He also started sleeping through the night at like 3 months ish so... That was nice. You will likely find a lot of advice out there, just weight it all with your own logical thought. No parenting strategy is gonna be that effective if you don't understand/agree with it. Also no strategy will work for every kid. If you are trying one approach and it's not working (after giving it a fair chance) maybe consider another approach.
4. Maybe a tired cliche but try to spend alone time with your SO. It's easy to get swept away in the workload of raising a newborn and you may start to feel like you are drifting away from your SO. You both are always tired and it's hard to really connect. It happens. And frankly its pretty hard to avoid. Just do your best to prioritize your relationship sometimes. That is the foundation of everything else and especially the foundation of your kid's life.
Otherwise, enjoy the ride! And if your not enjoying the ride, just remember that it's going to get better. I don't know you, but if you try, you will probably do great!
