How to get over dislike of MIL?

Looking for advice. Since having our baby this summer, I can't stand my MIL. Some of this is understandable as she's had a number of very outdated suggestions that contradict modern medical advice and she has been annoying in typical ways on visits.

That said, I don't want to be hung up on this anymore. I find myself randomly dwelling on my annoyance toward her on days we don't even talk to her. I cringe every time she texts us. This feels unnecessary given that we will probably only see her about 4x a year in person and video chat once a week. She means well and isn't pushy and so we can just ignore the bad advice. My spouse and I are well-aligned with our boundaries.

Has anyone found a way to let go of something like this? Thanks.
