Congratulations!
Having a child is the best thing ever, even though there is times you do not feel that. But they are few and far apart.

I am not gonna tell "do this, do that", but you will never feel ready, but you will adapt, very fast, and become the best parent you can be. That's it. Nothing else, never compare with others, everything and everyone is different.

The only advice I will give is, try to enjoy EVERY moment, as the it will never come back again.
Yes, waking up to a screaming child at 3AM to feed them is, at the second a nightmare, but while feeding it, it is the most precious time you have with it, so try to enjoy it, because very soon, it will never happen again.
But then, there is another thing that you can enjoy.

Good luck!
