Basic rules to follow if you're allowed the honor of being in someone's birthing space and this applies to EVERYONE including;
OB's, Midwives, Nurses, Anesthesiologists, etc...
It's actually sad that these things need to be said, but it does. Labor is a lot of work on the body so it's important to respect the birthing person and give them space, time, and peace needed to achieve a physiological birth.
