Does anyone else here have an annoying monster-in-law? How do you deal? haha

I let my husband handle anything related to my inlaws. For example, they commented about something related to how I manage our household, I'll just acknowledge their comments with a smile. And then I'll discuss it with my husband. The next time the same topic comes up, my husband will be the one to explain to his parents.

I'm lucky enough to have nice parents-in-law. I suggest you just shrug it off and don't the advice/nagging too personally. After all, they just want what's best for your family. If it really gets into your nerves, talking to your spouse might help.
