Why do I say that birth is an elimination process? Something large is within a body cavity and it must come out. When it’s time, it will come out. It will come out no matter where you are, no matter how smart/dumb you are, no matter if you want it to or not. Even if you want to call the whole thing off and come back to it another day, it will still come out. You’ll be very uncomfortable when the body messages say “It’s time“. You’ll get the right information from the messages of that discomfort and you’ll know exactly what to do. When you’re done, you’ll feel a lot better!
(Now, go back and read what I’ve said and apply it to vomiting, pee-ing, poop-ing or birthing and see how it fits.)
