If the first child is born in normal labor, the second child will have contractions once every 10 minutes after full term, and the intensity and frequency of contractions will gradually increase, usually within 4-6 hours of delivery, some even shorter, less than 1 hour. Usually, labor progresses more rapidly after the launch of the second child compared to the first child. One contraction in 10 minutes indicates regularity and may be a preterm labor. If the contractions are more frequent, lasting more than 30 seconds each, and more intense, the fetus will usually be delivered within 4-6 hours. Since the second child is delivered faster than the first child and the labor is shorter, if the membranes are broken after regular contractions, you can lie down and raise your buttocks and go to the hospital obstetrics department as soon as possible to wait for delivery. It should be noted that after entering labor, pregnant women should pay attention to keep their strength and avoid excessive tension and anxiety in order to facilitate a smooth delivery.
