VBAC: vaginal birth after caesarean

If you’ve had a caesarean before, you might wonder whether you can have a vaginal birth next time. For many people the answer is yes — it’s called a VBAC (vaginal birth after caesarean), and it’s a common, well-established option. Others choose or need a planned repeat caesarean. Here’s what goes into the decision, so you can weigh it up with your team.

“Once a caesarean, always a caesarean” is outdated. That old saying no longer holds. Many people who’ve had a caesarean go on to have a successful vaginal birth afterward. Whether VBAC is right for you depends on your history and this pregnancy, and it’s a decision made with your obstetric team, taking your preferences into account.

Who’s a good candidate. VBAC is often suitable if you’ve had one previous caesarean with a common (low transverse) type of incision, no other uterine scars, and no complications that make a vaginal birth risky this time. It’s more likely to succeed if you’ve also had a vaginal birth before. Your team will look at why you had your previous caesarean, your current pregnancy, and your overall health.

When a repeat caesarean is usually advised. A planned caesarean may be recommended if you’ve had more than one previous caesarean (depending on circumstances), a certain type of uterine scar, certain complications, or if this pregnancy has issues (like placenta praevia or a baby in an awkward position). Sometimes it’s simply your preference — and that’s a valid choice too.

The main risk to understand: uterine scar. The specific consideration with VBAC is a small risk that the scar on your uterus could open during labour (uterine rupture). It’s uncommon, but because it can be serious, a VBAC is planned in a hospital with the ability to monitor you closely and move to an emergency caesarean quickly if needed. Understanding this risk — and how it’s managed — is central to making an informed choice.

How a VBAC labour is managed. A planned VBAC usually means continuous monitoring of your baby’s heartbeat during labour, giving birth in a hospital with theatre access, and your team keeping a close eye on progress. Inducing or speeding up a VBAC labour is done cautiously, as some methods raise the scar risk — your obstetrician will discuss this if it comes up. Otherwise, labour can unfold much like any other.

The success rates and benefits. Many planned VBACs are successful. A vaginal birth generally means a shorter recovery, avoiding major abdominal surgery, an earlier return to normal activity, and often easier early days with your baby and future pregnancies. For many, that’s a strong draw.

If a VBAC doesn’t go to plan. Some people who plan a VBAC end up needing a caesarean during labour — because progress stalls, or for concerns about you or your baby. This isn’t a failure; it’s your team keeping you both safe, and you’ll have given your baby the chance at the birth you hoped for. Going in with a flexible mindset helps.

The repeat caesarean side. A planned repeat caesarean is a safe, predictable option many people choose, especially if VBAC isn’t suitable or they’d simply prefer it. It means a scheduled date and a known procedure, with the usual caesarean recovery. There’s a separate guide on what a caesarean involves and on recovering afterward.

Making your decision. There’s often no single right answer — VBAC and repeat caesarean each have pros and cons, and the “best” choice depends on your medical picture and what matters to you (recovery, future pregnancies, how you feel about labour, your previous experience). Your obstetrician will lay out your individual risks and benefits, and it’s a shared, informed decision. Ask all the questions you need, and take your time.

Processing your last birth. For some people, the choice is tangled up with how their previous caesarean felt — especially if it was an emergency or left them shaken. If that’s you, it’s worth giving yourself space to process it, perhaps with a birth debrief (going through your notes with a midwife) or by talking it through, so this decision is made from an informed, settled place rather than from fear or unresolved feelings. Wanting a VBAC to “reclaim” a birth experience is valid, and so is choosing a repeat caesarean because it feels calmer and safer to you — there’s no wrong reason, as long as it’s your genuine, informed choice. Your midwife and obstetrician can support both the practical planning and the emotional side, so don’t hesitate to raise how you’re feeling, not just the medical questions.

Whichever way you lean, a previous caesarean doesn’t automatically decide your next birth. Talk it through with your team, weigh what matters to you, and know that both a well-supported VBAC and a planned repeat caesarean can be safe, positive ways to meet your baby — the right one is simply the one that’s right for you.
