Congratulations. Your life will never be the same. My oldest is 19 now and just started working his first job. I will never forget changing his diaper for the first time in the hospital neither will my wife or the nurse that day back in 1998.
I put on latex gloves and a surgical mask. Seemed practical to me because they were on hand I was used to putting on a pair of gloves and respirator to protect myself from paint and fumes. Apparently it was overkill for a diaper full of shit in their eyes and I still hear about it today.
