congratulations to you and your wife for this wonderful and tense moment they are living, everything will pass soon and the 3 will be completely happy.
My experience as a father was wonderful, to carry it, to give it food, to sleep with the baby, to bathe it, everything is incredible and almost of in dream.
especially when they start to show their personality and customs, for example, you sleep in the car and when you get it out you are ready to play hahahaha.
It is indescribable everything that happens every moment is a completely new experience.
