A caesarean is a surgical procedure in which a baby is delivered through an incision made in the mother's abdomen and uterus. This type of delivery is often necessary when there are complications during pregnancy or labor, such as if the baby is in a breech position or if the mother has health issues that make vaginal delivery unsafe. The procedure gets its name from Julius Caesar, who was reportedly delivered via this method, and it's also known as a C-section.
