Quinn does not hate to brush his teeth like many kids with sensory issues, but he certainly doesn't love it. And he won't do it himself.
But that changed instantly when my husband downloaded the Disney Magic Timer app, which is miraculously free at the App Store. Kiddos choose a Disney or Marvel character (or scan an Oral B product from one of those companies), then they get to watch that character slowly appear on the screen over two minutes while they brush.
Quinn literally runs into the bathroom after breakfast and dinner shrieking, "I've gotta brush!" Amazing. Especially if you have a reluctant brusher in the house, I can't recommend it highly enough.
