Every incident requires a bandaid. A wipeout in the road causes a scrape. The fix is a bandaid. An imperceptible maybe jammed finger requires one too. It hurts. Therefore it needs a bandaid.

In this case, causation doesn’t matter. What matters is how to make it feel better. Early on, I found much success in kisses. They were an accepted method of restoring health for not serious wounds. The more real injuries Fleur obtained, the less acceptable kisses were to hurts.
Placebos are powerful tools for healing. The brain being suggestible can run with them and cause impressive healing. Medicine accounts for them in efficacy studies as any time the patient believes in the cure, they can heal.
Our placebo bandaid are a cheap box of 100 I found. They barely stick. And fall off after a few hours. Just after the toddler has forgotten about the injury. In fact, if the complaint persists past the placebo bandaid, then I misjudged the injury.
