We aren’t simply uneducated on how ears work, and getting unsolicited tips from childless people while already busy with our kids is just another stressor.

Well… considering I have 2 kids. You can put your bullshit “tips from childless people” garbage argument away. The source of the information is irrelevant if the information is true regardless.

Regardless that doesn’t negate the overall “common courtesy” theme of my post.
