From the day you bring your baby home from the hospital, your lives will change completely. Your wife's life will revolve around your baby, as it will take her time to recover from the birth and get used to the toll breast feeding takes on her body. During this time, your frustrations as a husband may build up without you even realizing it.
This is your first hurdle. Even if your life centers on your job, you should try to increase the amount of time you spend touching your baby, even if by only a little bit.
You have only just begun raising your child. Don't leave childrearing duties to just one parent-work together with your wife to build up your experience as mother and father.
