YTA…

As someone 38 weeks pregnant, I’ve definitely confided in friends and family who have had their own children to gain an understanding of their experiences but pregnancy and birth is different for everyone so constantly bringing up their experience for personal gain can be re-traumatizing to them. Your SIL obviously did not have an easy birth experience and, on top of being hormonal, is being constantly reminded by you asking about the experience. Allow her time to process and understand her experience; she needs time to mentally heal also.

I HIGHLY suggest you start doing some online research (if you haven’t already). Check out fearfreechildbirth.com. There are lots of materials you can read and listen to that may help you mentally prepare yourself for what is to come. In the end, just keep trying to remind yourself that the pain and everything that comes with childbirth is temporary. However, you may gain PTSD from the experience as well so be looking for a possible postpartum therapist that can help you work through the trauma.
