Congrats. Our first was just born on February 8th. Holy cow can these little suckers test your patience.
As your wife plans on feeding, you'll probably get to find out that there isn't a whole lot you can do early on other than change diapers and attempt to sooth the baby when the feeding is done. I've basically become a servant as my wife is stuck in a chair for 30 minutes to an hour at a time.
If you have the ability, I'd suggest arranging possibly separate sleep situations. The whole breastfeeding thing seems to feed them the notion that you simply can't use bottles until they are latching properly. Basically means, you can't do anything when they're hungry. I suppose in a month or so that may change, but I have to say, as a guy, there just isn't much you can do in the first month other than general household things.
Congrats again, and good luck!
