1. One of you (your wife or you) needs to be fully available for taking care of the baby. If both of you need to go back to work right away (probably in America), then you will need a good Nanny who has experience taking care of infants.
2. You cannot wing it. Infants need a lot of attention even though they just sleep and poop all day. Again, one dedicated person needs to be there for them.
3. If you work from home, even with a dedicated caretaker, it will be ideal to have a closed door office/room where you work. You cannot work with a baby close by unless you absolutely have no choice.
4. Depending on your baby, you may have many sleepless nights in the beginning. It cannot just be your wife doing the sleepless nights. She will need your support which translates to "waking up randomly to check on your baby who is crying in their crib"
5. Do some research on this horrible thing called SIDS. Hopefully none of us never ever have to deal with it but it happens to people. Protect your baby as much as possible against SIDS by following a few basic but important rules.
6. Make a list of chores that are needed specifically to take care of the baby and divide the work between the 2 of you. Don't leave things for guessing even though be willing to change things at last min. Pro tip: No matter how much you plan in advance, a baby will make you change things at the last minute. Nature of the beast :) but still plan.
7. Family Support: If you can, get help from immediate family as needed for both emotional and physical support. You may not realize but even a 30 min. break away from the baby can do wonders to your emotional well being. Babies are tough and they will test your patience. That's ok. Just learn to find some time away from all of it. Family members specially moms/dads are the best way to address that if you are lucky enough to have them close by.
8. MOST IMPORTANTLY: Don't worry about things too much and most babies turn out fine. So enjoy the little moments with them as they will grow up so fast that you wouldn't even believe it. You can never be a perfect dad or mom. But you can be a dad. Just be there. Show up. That's the most important thing. All the best!!
