Handling Opinions from Family

Anyone dealing with family/in-laws that feel you’re overprotective in general (or due to pandemic) and question other random choices you make in regard to parenting? I also just received advice about whether I should have a boy or a girl as a second baby based on my temperament; and, of course, advising that I definitely have this second baby, because I will then be less protective of my first🙄🤯. I know how to regulate myself in the moment, but am having a lot of difficulty with letting this go/letting it affect my relationship to them overall. How are others doing with unwanted, rude opinions?
