The chances of having a cesarean section for the third child increase significantly when both births were by cesarean section, but it is not always necessary to have a cesarean section. This situation needs to be considered based on a variety of factors such as the size of the fetus at full term, whether the position of the fetus is normal or not, and whether there are various pregnancy complications or co-morbidities. However, in the following cases, a cesarean section cannot be performed even if the interval is eight years since the last cesarean section. 1. If the reason for the first cesarean section is due to pelvic stenosis, the pregnancy will still require a cesarean section in this case. 2. If there is a history of difficult labor in the first and second child, this situation also can’t be normal delivery, and cesarean section is needed. 3. In the second trimester of pregnancy, there is a lack of oxygen in the uterine cavity of the fetus, or the pregnant woman and the fetus are at greater risk, and it is necessary to give birth as soon as possible in the state of Cesarean section in a timely manner. If there is no abnormality in the pregnancy test and the indications for a normal delivery are met in the second trimester, then it is necessary to coordinate and communicate with the local doctor, who will carry out a detailed examination and evaluation before judging that it is safer to choose a more suitable mode of delivery.
