What better way to show cardinal movement, rotation of a baby through the pelvis, than by demonstrating with The Baby Way, manufactured by BirthWorks International. This is an “Ah Ha” moment for any pregnant woman, helping her to understand the importance of movement in labor. Our imagination is much more powerful than we may realize. Showing a baby doll fitting snugly through a pelvic model, even if cloth, still gives the impression of a tight fit. When women feel their own pelvises in BirthWorks classes, they can experience and imagine more space that is there for their baby to move into. Then when they see the diameters of the pelvis in The Baby Way, they understand how the baby rotates to move through the pelvis in optimal pelvic positions. This is a powerful connection sure to have a great impact on any woman giving birth. The Baby Way is a must have tool for anyone birth professional including childbirth educators, doulas, nurses, doctors, and pregnant woman.

The diagrams below show the pelvis in an upright position which is optimal for birthing. Note that the pelvic inlet is wider from side to side. Since the widest part of the baby is the shoulders, the baby must enter the inlet and then tuck his chin to turn 90 degrees so the shoulders can pass through. In contrast, the outlet is wider from front to back. Therefore, the baby must turn 90 degrees once again to move his/her shoulders through the outlet. Turn the head into a breech position with feet first and demonstrate how a breech baby also turns and rotates to pass through.
