We’ve had 4 babies. 2 with doulas and 2 without. The 2 with doulas had a sense of peace and calm in the hectic atmosphere. Mary Susan brought reassurance and support and even joy.
My biggest fear was the delivery would not go smoothly and I would not know what to do. This was based on experiences of our first child where decisions were made in panic and there was no calm third party person.
It was helpful having someone else in the hospital who was not as emotional as me. My wife would never be alone and someone could advocate for her hopes if I had to run to move luggage, park a car, get other kids or go to the bathroom. I’m glad my wife was never alone.
