Is this question directed to me? I was asking the author of the post, because, in real life, I often hear women state this: they say that after you have a c section, all future deliveries must be done by c section. And I was wondering if it's just an ubran myth.
The "Risks to future pregnancies" section of the link you sent, says "Most women who have had a caesarean section can safely have a vaginal delivery for their next baby, known as vaginal birth after caesarean (VBAC). But sometimes another caesarean may be necessary."
Note the 'most' and 'sometimes'! I wonder if there's a causal connection, i.e. if having a c section increases the chances that your next delivery must be done by c section too.
