Is it true that if the first child was born via C-section, the second child must also be born via C-section?

Patient's question:

No

Doctor's answer:

The first child was delivered via cesarean section. Whether the second child can be delivered vaginally depends on the following factors: whether the cesarean section was more than two years ago, whether the fetus is too large, and whether the uterine contractions and birth canal are normal during delivery. If they are normal, a vaginal delivery is possible. If the first child was delivered via cesarean section, it is recommended that the second child also be delivered via cesarean section.
