C section shaming

I hope it’s ok to post here.

My sister in law is a midwife. She is predominantly a home birth midwife and very against any medical intervention for birthing.

My first pregnancy, 7 years ago, ended in an induction for hypertension. Unfortunately due to my baby being posterior/asynclitic/brow presentation/double nuchal cord, I didn’t dilate and my baby’s heart rate decelerated. He was born via emergency c section. My second, I had a scheduled c section due to a cesarean scar defect. And my third, well I just followed suit with the first two. My babies are here and healthy and while I would have loved to avoid surgery, it is what it is.

Every time I see my sister in law she makes a horrible comment about the births of my children. Often it’s less direct (“oh I love it when elective c section babies decide their own birthdays and come before their scheduled date” - mine never did). But sometimes she’s just blatant about it (“your children wouldn’t get sick if you’d have a vaginal birth”).

Aside from this she’s a lovely person. And I hate conflict so I don’t mention it and just ignore her comments.

Im not really sure what I’m asking but I figured you all would know best. What can I say to her to nip this in the bud? Im getting kind of sick of it nearly 7 years on!
