my parental abilities

No parent gets it right the first time. I suspect not even the second or third! What's important is being there for your wife. The moments right before and right after giving birth are incredibly difficult and exhausting so support her in any way you can. Sleep deprivation will turn you both into monsters so just go with what keeps you both sane. Sometimes you'll hear people tell you you have to do this or that to be a good parent... but honestly, happy mom & dad = happy baby. Don't be too pressured; just do what you can :)
