During descent in the second stage, the baby typically rotates into which position?

• A. Occiput anterior
• B. Occiput posterior
• C. Occiput transverse
• D. Face presentation

Answer: (A)

As the baby descends in the second stage, the head undergoes internal rotation to align with the birth canal. The position that the head most commonly assumes at delivery is occiput anterior, where the back of the head faces the mother’s front. This orientation lets the head flex so the smallest diameter presents first, making the descent and crowning smoother and usually easier for the mother. Occiput posterior or transverse can occur, but they’re less favorable and often rotate toward anterior before birth; face presentation would require the head to extend markedly and is not the typical rotating position in descent.
