My sister had a problem with stitching after her first, and she didn't have sex for something liek 9 montsh afterwards. If she had done something about it immediately post baby, she would have been able to get it done withoutgoing on the waiting list, but she was sick of people looking at her bits, and opted to let it heal.
So she has had a nother baby, and I think it all went OK re the scar.

I had an episiotomy, and my dr said it was "a nice job" LMAO. Even then it still hurt for a good 3-4 months after baby, and it was using tampons that stretched it all out for me. So even though the idea of stretching it might not appeal to you, the occasional finger workout might go a long way to making things more bearable in the meantime.
