Enjoy each and every phase. Soon enough she'll sleep through the night, so enjoy the hours with her in the middle of the night until she does. She'll say her first word and then they'll start to come in torrents. She'll have her first date and you'll want to destroy the boy if he looks at her wrong, then someday she'll find the boy she wants to spend eternity with and you'll rejoice.

Enjoy it all. Every step of the way, the good things, the bad ones. She'll think that you can do anything and then learn that you can't. And both, in their time, is the right thing for her to believe.

P.S. Understand that from the very first day she has a functioning brain and is using it. Watch closely and you'll see her figuring out how to use her hands, how to make sounds, how to mimic what you do. I had a blast with my daughter making faces at each other long before she could even sit up. She really liked sticking her tongue out and would smile when I did it back. We would do it to each other repeatedly until she decided to try something else.

It's your job to figure out what she is trying to tell you (even from day one), it is not your job to decide what she is saying.
