Since some are being realistic, forget advice. First three months are all about survival, for you and your wife. Get through that first. Get as much help as possible. But keep your eyes on your kid at all time. The kid is your responsibility. Something goes wrong, you are it. Don't let the kid out of your sight You can trust your wife, but still have her in your sight. Your wife might be on an emotional rollercoaster, or not. Better to be read to help her than have her have an accident.
Raising the kid, that's another story. You might have some ideas as to what you would like to do. But depends on the kid, it might have to change or modified. One thing I did was not trusting anyone when it came to my kids. I had my eyes on them. Never allowed any single adult to be with my kids at any time without my wife or I. My kids are my responsibility. Just loving them doesn't work. Just giving hard love doesn't work. You have to be flexible. Some rules, don't bend them. But set it so you can forgive. It's a lot like driving. You can be the best driver, but there are other people driving like crazy around you. Keep 'em safe, but don't let them know you are always there. They need freedom and breathing room to grow. But be ready to catch them before they fall on their head. It's a lot like juggling. Yeah, they need to know you are the dad. But they also need to know they can count on you to listen to them when they need you. You have to be their dad, and a friend, and a good cop and the bad cop. You have to be their everything without them expecting you to solve everything for them. It's hard. But it's worth it.
