Massive, enormous, humongous congratulations to you! My wife and I had our first on 8/21, a daughter as well.
It's the best, I can't even come up with words to describe it, it's just simply the best.
Hope you got a good sleeper!! If you guys are planning on swaddling, we tried using those swaddle blankets by Aden and Anais, but she kept squirming out of them and the blanket would end up around her face in the middle of the night (some serious freak outs occurred) so we then bought these sleep sack/swaddle blanket combos (link at bottom). They are great because they are Velcro so she can't wiggle out of them, the blanket won't go around her face, and she has plenty of room to kick her legs (one issue people have with swaddling is that if you swaddle the legs too tight and they can't kick, it can cause hip problems, so the fact that this is a sleep sack with tons of room in the legs is absolutely ideal, maybe Jackso can touch on this from an orthopedic standpoint). Anyway, it's the one thing I would buy for anyone having a baby.
Good luck buddy!! And don't forget, no baby ever died from crying. When you get pushed past the brink of frustration at 2 am (and you can will), and the baby is wailing, put her down and walk away. And every single parent feels that same way where the cries make you insane, so don't feel bad for feeling this way (nobody ever told me that).
