With the experience of the birth of our first child last January (and chats wih other daddy friends), let me share a few points on the life of a new dad for my friends with due dates on their mind:

• Your wife's head will look a lot bigger (looking at your tiny child's head all the time makes everything else look huge)
• Changing diapers really is non stop (at least the first month)
• It will get very hard to talk about anything else but your baby (sorry guys)
• You'll notice babies and kids all around you all the time and won't believe Japan ever had a falling birthrate.
• You'll need to be more creative in bed (it's not recommended to have sexual intercourse for 3 months after birth -linked to ovarian cancer, infections...)
• You will never have been so happy to have your parents or in-laws close by.
• Your wife will forget you are her husband and just call you "papa" or "daddy".
• You will act like you own the sidewalk and people should give you priority on everything.
• You will think of death, pain, helplessness a lot more than before.
• You will want to build a house with your own hands.
