In addition to being a long time PA member and someone who has taken and appreciated all your mat classes...I am a certified childbirth educator, prenatal exercise teacher, doula and midwife. I'd like to encourage you to describe the arrival of the baby as a "birth" rather than a "delivery". Consistent with the philosophy of PA it makes the practitioner (in this case the mama) the protagonist rather than whoever is on the receiving end. We have a joke in the midwifery community....delivery is for pizzas!! Hope you'll consider this "modification" in the upcoming classes.
