Introduction
For first-time mothers, delivery usually occurs within about 1–3 hours after cervical dilation reaches seven centimeters. At this stage, the second stage of labor has begun, characterized by stronger and more frequent contractions. The mother should cooperate with healthcare providers by pushing effectively to facilitate the baby's delivery. If there are signs of weakened contractions, abnormal fetal heart rate, or labor progression arrest, it is important to promptly inform the medical staff for appropriate management. For first-time mothers, the second stage of labor begins when the cervix is fully dilated and ends with the birth of the baby.

After the cervix dilates to seven centimeters, first-time mothers usually give birth within about 1–3 hours. At this stage, the second stage of labor has begun, with stronger and more frequent contractions. The mother should cooperate with medical staff by pushing effectively to help deliver the baby. If contractions weaken, fetal heart rate becomes abnormal, or labor progression stalls, it is important to promptly inform healthcare providers for appropriate management.

For first-time mothers during the second stage of labor—from full cervical dilation to delivery of the baby—the process typically lasts 1–2 hours. When the cervix reaches seven centimeters, it is nearing full dilation. Contractions occur every 1–2 minutes and last 50–60 seconds each, with increased intensity helping to push the baby downward. Most mothers complete delivery within 1–3 hours at this stage.

Progression of labor is influenced by factors such as contraction strength, fetal position, and maternal physical condition. With strong contractions, normal fetal positioning, and adequate maternal energy, labor may be completed in about one hour. However, if contractions are weak, the fetus is in an abnormal position, or the mother is fatigued, labor may take longer—but generally does not exceed three hours—and requires close monitoring by medical personnel.

During this phase, the mother should remain calm, follow medical staff instructions for breathing and timing of pushing efforts, and avoid uncoordinated exertion that wastes energy. It's important to stay hydrated and consume easily digestible foods or supplements such as chocolate or energy drinks to maintain strength. Any discomfort should be communicated promptly, and the mother should cooperate fully with medical procedures.
