Entry into the birth canal is one of the most critical stages of labor. Broadly, here's how it happens:
The cervix ripens and opens: Once labor begins, contractions soften, shorten, and open the cervix. This opening usually reaches about 10 cm, which is the width needed for the baby to pass through.
Baby's position and descent: The baby usually turns head-down (head-first position) and gradually moves deeper into the pelvis. The head engages in the pelvic inlet, the narrowest part of the birth canal (formed by the vagina and pelvis).
Descent and adaptation (flexion and rotation): The baby's head bends forward (flexion) and usually rotates slightly to fit the curves and narrow spaces of the birth canal. This helps the head's smallest diameter pass through the canal.
Entering the birth canal: Once the cervix is fully open (full dilation), the baby's head moves into the upper part of the birth canal (the vagina). At this point, you'll usually feel the urge to push. The baby moves through with their head first, and delivery happens.
In short: contractions push the baby, the baby flexibly adapts their head to fit the canal, and they pass through the pelvis to be born. Every baby makes this journey at their own pace and in their own way.
