Get that kid on a schedule. And make sure your wife breast feeds so you don't have to do anything in the middle of the night. :)
Am 100% serious on the schedule. The first few months will obviously be rough. But our daughter was waking up only once in the middle of the night by 2 or 3 months. Was sleeping through the night by 8, and it should have been earlier than that.
Get used to early morning workouts. I'm almost always done with my first workout by 6:30 or 7, as my wife leaves for work by 7:10.
That being said, always be prepared for things to change. Teething, sickness, growth spurts can throw a wrench in things for a week. You just have to be able to adjust.
