Yah, they're all unecessary. Know kids in their teens and 20's that never got one and thrive compared to their cohorts.
Same goes for the K2 they're going to want to administer to the baby under fear mongering of they might bleed to death on the drive home from the hospital... which you shouldn't go to for a birth. Birthing is not a medical procedure. It's a natural process that every woman's body knows how to prepare for and execute independently. Ergo no to the epidermal, it's what creates the self fulfilling prophecy of difficult births and subsequently the qualifying label beforehand of high risk pregnancies.
Don't sweat it dude, you got this.
Just use common sense and listen to your gut feeling, it's right 95% of the time.
Welcome to a new life and don't forget to enjoy the ride, it goes fast!
