Tons of good tidbits of information in here already so I wont go too crazy.
But I will emphasize what I think the BIGGEST and BEST advice I received but also experienced going through it twice with 2 Covid babies
"Everyone has a better way of doing it" - After spending over 8 weeks in the NICU with my first I think the most frustrating aspect of it was the fact that just about every nurse had their own preference in the "best" way to:
swaddle
change diaper
which formula is better
which diapers are better
how to soothe the baby
how to hold the baby
how to breast feed the baby (3 different consultants helped my wife, all said something different and discredited the previous one)
This led to some serious post partum depression for my wife because she felt she could never do it "the right way" or the way she was being told.
With our 2nd child we just did it her/our way and it was far more relaxed and controlled.
So if I had to reiterate and give 1 big point of advice it would be:
"You'll figure it out whichever way works best for you, and enjoy every minute"
My boys are now 3.5 and 1.5 and its gone by so fast it scares me.
Just support your wife and be there when you can, take care of her while she takes care of the feeding the little one for the first few days.
You'll nail it
