Wash Your Teeth
This has happened a few times with our youngest. You can tell him to go wash his hands for dinner and by the time he gets to the bathroom his ADHD brain has been around the world and back and to far away galaxies that he has forgotten why he is in the bathroom. So he sees the toothbrush and thinks that he is suppose to brush his teeth. Hence “Toothpaste” taste buds.
take care,
