The time needed from the opening of two fingers of the uterine mouth to the delivery of the second child is 4-8 hours, but the exact time needs to be decided according to the individual physical condition of the pregnant woman, the reaction of contractions, the condition of the cervix, the state of mind as well as the condition of the fetus and other factors, and the time needed is usually a bit shorter than that of the first child. If the pregnant woman’s mental state is good, her contractions are strong and regular, her cervix is looser, and her fetus is smaller, the labor goes smoothly and the labor time is usually shorter. If the pregnant woman’s mental state is poor and her emotions are tense, and at the same time, her contractions are weaker, her cervix is tighter, and her fetus is larger, the labor may not be conducive to the labor, which may result in a longer labor time. Depending on the individual situation 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 appropriately in between contractions, thus replenishing their physical strength for the subsequent labor. At the same time, appropriate exercise, such as walking and sitting on an exercise ball, can promote the opening of the uterus, which can help speed up the labor process and shorten the time of labor. Avoiding excessive anxiety and tension and maintaining a good mental state can ease the pain caused by contractions.
