Most births that are born fast are usually uncomplicated births. Have the best qualified person deliver the baby. In this case, it would be you, the father who attended my birth class. Park the car in a safe place and place the mother to be in the back seat of the car. Make sure your hands are clean and have a towel or a clean cloth like your shirt ready to use to wrap the baby. When she delivers, just catch the baby. Make sure he cries and put him on his mother's breasts. Cover and keep him warm. No need to cut the umbilical cord or pull on the placenta. Just drive them safely to the hospital.
Congratulations, you just delivered your baby!
