Hello everyone, I'm arguing with my mom about whether or not to cut her hair while pregnant. Mom insists that it's bad luck and that hair carries life energy, if you trim it you can shorten your child's lifespan! I think this is just a stereotype someone made up without any basis and now everyone follows it ??‍♀️. Hair is also the same as nails. So shouldn't we stop cutting our nails for nine months too? In general, I don't know ??‍♀️
