My son loves to sing. He sings so much and so often that we've blocked it out.
Well we blocked it out until last year when he decided to sing Let It Go at his school's talent show. He did an amazing job. That's not just proud mama, many people told me so.
He hasn't stopped singing. He still sings all of the time. We don't block it out any more but it's more like background music.
Every so often he starts singing and I have to stop to listen.
