So sorry to hear about your loss. That is a whole lot of emotion in just about every direction.
Be sure to take moments, frequently, and just breathe. You are strong enough to be there for your pap, and for your wife, and still get this new job started on the right foot....provided you breathe and set down the bags of one room before you enter the other. Does you no good to worry about your wife or pap at work. Does you no good to worry about work while you're talking about the little one on the way. Doesn't mean you aren't holding all of it in your heart 24/7, you just aren't holding it in your hands constantly.
Congrats on the baby.
