My daughter will not stop humming!!!

Leah

She’s 11 and loves to sing. She hums constantly and when we are out of the house for hours it’s non stop. And she is like a broken record humming the same song or even the same spot in a song over and over. To me, it’s like a fly is constantly buzzing in my ear and it triggers anxiety in me. I try to nicely tell her to change the song or stop for a second but it works for 1 second. I had a coworker like this before and I had to move desks because it drove me insane. I feel so guilty for feeling this way.
