I’m not a parent, so I’ve no advice to give except “get as much sleep as you can” that other posters already mentioned.
So, congrats, good luck, don’t be afraid to let other people deal with the mess if you feel too stressed sometimes, and have fun! 
Just something I’ve recommended before to all new parents:
Pick a special spot, someplace you can take the young’n to every year sometime around their birthday, and take a picture of the little tike next to “his” tree, or “her” bridge, or whatever.
You’ll really enjoy having those pictures.
And, like others have said, it goes fast! Moms will be looking up to their sons by the time they’re teenagers (on average). Dads will be fretting about their daughters long before their first date. It will seem like just last week they were talking their first steps when they start talking about taking driver’s training (Oh God! My baby!)
Enjoy those times while they’re still itty-bitty. They’re over way too quickly.
And, just wait until they say “Wuv you” for the first time.
I dare you not to cry. I dare you.
Ooohh!! Oooohh!! Babies!!! I’m having a(nother) baby next month, too! I’m so excited; it’s all I think about. Like others have said, babies are tougher than they look, so don’t drop 'em on purpose (of course), but don’t panic whenever he gets a boo-boo. Don’t worry about a feeding schedule, if he’s hungry, he’ll tell you. I can tell a new mom because she’ll wake a sleeping baby to feed him. That’s just silly. If he’s sleeping, he’s happy, and you should be, too. (Happy and sleeping).
Here’s one that I don’t think has been put out there yet; keep the baby gear. If neither you or your husband are sterilized, you never know if you’ll need it again. I’d also recommend neutral colors for the most expensive things, but with just a month to go, you’ve probably already bought everything. We had planned to stop when our daughter was born (six years ago) but these things happen, and could very well happen again. We’d already given away all the old baby gear so I got the fun (and expense) of buying all new stuff, because we couldn’t very well expect a shower for our third (or fourth or fifth if it comes to that).
Congratulations! I’m expecting my first child (a boy too) due on April 3rd. He was an unexpected surprise but I’m already in love.
I’m feeling all the same emotions you are so I guess we’re normal. All I can do at this point, is to wish us both a coupla healthy boys to bring home.
Thank you sooo much everybody! I appreciate all the tips and the “take it easy” reminders. Congrats to all the other soon to be mommies and daddies. and yes dhk, you missed the naked under the full moon party in my backyard… did you not get the memo?
