Ok, a couple unsolicited tips.
The girl is going to start nesting. There's nothing you can do about it, except put up with it. I know you don't need a crib for nearly 9 months, and you know it too, but she's going to want one next month, and it damn well better get assembled and be ready to go the moment it comes through the door.
Get a small radio and put it in with the baby, leave it on ALL the time. Then they get used to a certain level of noise, and you don't have to creep around the house when they are asleep for fear of waking the monster.
Every girl WANTS a $1000 stroller and matching car seat. Don't skimp on the car seat. I've gotten more mileage out of the generic $5 stroller that we picked up at a thrift store because we left the $1000 monstrosity home by accident.
Start keeping a different schedule than the woman now. If she goes to bed early and gets up early, you go to bed late and get up late. The smaller you can get the window where you are both asleep, the better.
Go to the prenatal classes. Try to find one run by a midwife our doula. The ones run by the hospitals are decent, but the ones run by the professionals are fantastic. You will learn stuff that will help, like what to pack.
Similarly, take the tour of the local maternity ward. You don't want to be wondering where the entrance is, what floor it's on, or what's the most direct route there when it's time.
It's ok to lie to her when she's in labor. And don't panic when she goes into labor, it's virtually always slow - as in, 18+ hours - for the first time. So get all your stuff together, pack her into the car, pick up food on the way to the hospital, don't speed, drop her off at the entrance and go park the car at some cheap parking.
Do everything you wanted to do now! Do everything you enjoy doing now twice as much and make a mental note of it. Buy anything you might want now. In 9 months your life will change forever. Goodbye Money, Goodbye free time. Best of health to your new baby and mother. That's all that matters.
