quick reminders: Ins companies now will cover breast pumps. (Obamacare).
Work out a schedule with your wife. Our Dr wanted us to feed our baby every 2 hrs until he started gaining weight and got rid of his jaundice. Took about 4 days to really stabilize his weight after leaving the hospital. I would take 4 hr shifts so she could get some sleep and not have to breast feed every two hours.
Make sure someone else cooks and cleans. Your wife will need to recover the first few weeks.
Try multiple diaper brands. Cheapass Whitecloud from Walmart fits/works better than Huggies for my kid. Deal sites (slickdeals, amazon mom, fatwallet) for trying to find diaper deals.
Everybody's got an opinion and will offer it on what you should do in every situation. In the end it's your child, enjoy all this time. It goes fast. Take lots of pictures/video.
And if you want to get some professional photos, between 7-10 days after birth is a great time to get shots. Baby will sleep posed while the photographer can get their shots ready. Zod may be able to expand on this.
Get him this: (heh, mine, 7 monther, just grew out of his)
Serious note: Talk to wife alot about how she is feeling (for months). Post-partum is a real issue with lots of women. I personally would look into counseling over drugs if she is feeling depressed or 'off'. Don't just assume she's tired.
