Grats bro, welcome 2 the proud parent club
first year is a bitch, the kid will have no concept of anything... and the worst part of it being sleep. your woman might get up and deal with it now, but after a couple months she's gonna start getting uber stressed from lack of a proper nights sleep. if your girls breast feeding she prob uses a pump and keeps milk ready and bottled, get your ass up and help her out now and then, you don't want her getting worn down and getting uber stressed out.
once again, grats bro.
