Hi @Rubberyduck , I am a midwife. I have facilitated plenty of VBACs and plenty of elective Cesarean Sections after a CS.
A lot of people here are trying to tell you that you didn't fail for not giving birth vaginally to your first child. They are missing the point. It is not about whether you "failed" or not, it is about how you feel, and what you need. You are still grieving for an experience in the past that you felt was not what you wanted. This new experience (your second birth) can indeed help you heal, or start the healing process, of that trauma. You are right in trying to plan for the best possible outcome
In my experience as a midwife, what matters in the end is not how you birth your baby, or what happens during the labour and birth. It is not even "just about having a healthy baby and healthy mum". The only thing that matters in the end is that the mother felt listened to and respected, and that her choices were heard and acted upon.
No one can tell you what will be the "best option" for you. But there are things you can do to increase the chances that you will heal emotionally and mentally from your first birth. Whatever you choose, you need to make sure the health professionals who are with you are respectful and they are on board with your choices, even if these change in the middle of labour. Talk to the midwife and obstetric team and explain to them how much you have been affected by the experience of your first birth. Make sure you trust the people in whose hands you will be if things go wrong. Both a repeat CS and a VBAC have risks and benefits for you and the baby. But you are not the person who needs to worry or react to these risks: midwives and obstetricians have been trained to deal with things going wrong during labour and birth of any sorts. They will do their job. YOUR job is to lay out your care, surround yourself by a team (your birth partner(s) that will be your advocates when you're too vulnerable to be assertive with your decisions, to take care of your body the best you can so it is as ready for the birth as it can be, to sort out childcare for your other child, to get things ready for this little human being who is coming.
One thing I find helpful for mums who had a traumatic first emergency cesarean and are considering a VBAC is to plan to have a low threshold for another CS: give it a go, but if things start to go wrong (if the baby is back to back, if there is fetal distress, or simply if you decide you have changed your mind), you will be given a CS as soon as possible. No faffing, no insisting to "keep going for a bit longer". You can agree to an early epidural if that's what you want. Put a plan in place with your team so you can feel confident with the process, and can change your mind if you start regretting it.
Once you feel reassured that you can change your mind, you may find your strength to attempt a vaginal birth increases. I have had plenty of mums very happy with their VBAC. Equally, I have had plenty of them happy to choose an elective CS. And I have had both types regretting their decision. The regret factor was always due to feeling the choice was not truly theirs.
Most of the trauma of birth is not about what happens, which often is inevitable, but the attitude of the people who care for you while it happens.
Whatever you decide, I wish you the best experience possible. please come back and let us know :)
