I've heard the neonatologists say that they make the parents repeat back, write down, and sign a consent form that says "I understand that refusing the vitamin K shot significantly increases the chances of bleeding, including brain bleeds that can lead to significant disability or death."
Not many people seem to want to sign that form for some reason.
All i have is OccupartionalFirstAid Level 1 and it drives me absolutely insane with frustration to think about what things real health professionals worst fears might be.
