An animal giving birth will postpone the birth until she feels safe and protected. A human mother also needs to feel safe and secure to birth normally. Too many people can inhibit the behaviors that will make for an easy birth. A birthing woman may feel more comfortable if those present at the birth stand behind, rather than in front of her. She might be most comfortable giving birth, cradled in the loving arms of her partner.
Language stimulates the neo-cortex.
In a hospital setting, a birthing woman may be asked precise questions that are impossible to answer without using the neo-cortex. A woman's partner, midwife or doula can play the role of protector, answering questions, outside the room if possible, for the birthing woman. Bright lights also increase neo-cortical activity. Dim or turn off the lights. This is another way of allowing the birthing woman to tune in to her inner resources rather than focusing on the world outside.
