A) She's afraid of a long labour ( I was 15 having my eldest while living at home, was in slow labour for 5 days and 17hours active labour but my daughter was born stargazing which wasnt picked up until she was coming out)
Fear of childbirth is a recognised mental health condition. Jog the fuck on.
B) She doesn't want to tear ( no idea where this fear has come from 🤷♀️)
Does it matter where the fear has come from? What is the problem with her being concerned about the possible long term physical health conditions that can result from this? Is she not allowed to make an informed decision about this?
My argument is that...
1) Recovery from surgery can take longer for fibro sufferers
Her choice
2) Anaesthetic/ epidurals don't work as well on us either
She will be best advised on this by a doctor not you.
3) She lives 30 miles away from us, near her husband's family and knowing my sister, she will expect us ( our mum at least) to be there every day ( mum has fibro, ms and 2 Foster kids of school age plus my elderly grandparents who we both care for)
She might not have this option under the circumstance, and you are a) making assumption b) your mum is capable of saying yes or no to this request c) 30 miles? And? Thats not that far if she really does need help. Which she might not need (nor indeed actually bloody want once the baby actually arrives)
4) With all the uncertainty regarding covid, she will possibly be in hospital alone for a few days after the birth
And? Her choice. She might be out in 2 days with an ELCS. She could have complications from a natural birth (especially if she has a EMCS) and end up in hospital for longer anyway. There are no guarentees either way.
Under the circumstances if she isn't allowed a partner there during labour - which could be several days, in theory that might mean shes in longer alone than if she has an ELCS anyway!
5) After trying for so long I dont understand why she wouldn't at least want to try a natural birth?
What the fuck has waiting to get pregnant got to do with method of birth? Why SHOULD she want to try a natural birth? Stop imposing your birth evangelism on her.
Maybe part of the reason for not getting pregnant has been stress over the birth bit of the picture. It doesn't mean she somehow wants a baby less.
Sorry but outdated backward views like your, in which you think you know better than another grown woman, really really boil my piss.
Butt out.
Otherwise you are headed for a breakdown in your longterm relationship with your sister.
