The time required from the opening of two fingers to delivery for the second child is 4-8 hours, but the exact time needs to be decided according to the pregnant woman’s individual physical condition, contraction reaction, cervical condition, mental state and the condition of the fetus, etc. Usually it is shorter than the time required for the first child. If the pregnant woman’s mental state is good, her contraction response is strong and regular, her cervix is looser, and her fetus is smaller, the labor time is usually shorter; if the pregnant woman’s mental state is poor, she is emotionally tense, and at the same time her contraction response is weak, her cervix is tight, and her fetus is larger, it may not be conducive to labor, which may result in a longer labor time. Depending on the individual condition of the pregnant woman, the time needed from the opening of the uterus by two fingers to the birth varies somewhat. After the opening of two fingers, pregnant women can eat or rest properly between contractions, so as to replenish their strength for the subsequent delivery. At the same time, you can do appropriate exercises, such as walking and sitting on an exercise ball, which can promote the opening of the uterus and help speed up the labor process and shorten the delivery time. Avoid excessive anxiety and tension and maintain a good mental state, which can relieve the pain caused by contractions.
