Community College. Child Development. Best 3 months you'll ever need. Covers their growth and development as well as parenting techniques to an extent. It's better to understand why the baby is the way it is, to understand how to handle it. Basically, girls are no different young, but they'll potty train faster.
You'll be nervous, but just remember to support the head and neck when you hold her, don't put her to sleep on her stomach, put her to bed on her side or her back, preferably her side (get those things that hold them on the sides to do this) and, sleep while the baby sleeps. There's great tips for colic that you can find on some good baby sites *these are geared for moms, but the info is helpful to ANY new parent* and there's other suggestions if you're bottle feeding etc.
Learn what her cries mean. You may think this is impossible, but you'll be able to tell when she's crying because she's wet, colicky, or if she's just tired. There will be subtle differences. Learn them fast and well. Most of all, spend as much time as you can with her. Baby talk, smiling, etc are all great ways for her to get to know you. Invest in a lot of burp cloths. You'll find you'll become used to being puked on, peed on, etc.
Bathe her in the sink with a sponge, careful the first few days before the cord stub falls off.
I could go on forever, here.
