Thinking, really the "overthinking" sometimes is related to anxiety and a sense of lack of trust. This sometimes leads us to "control" so much that it disrupts the "flow".....flow of your beautiful oxytocin which helps your uterus to be so amazingly powerful. Efficient in its work of labor. Remember......birth is so much about surrender....the ultimate TRUST in yourself and your babe and your body and above all God's great design. Which is pretty close to perfect, I might add.
