[Question] Should you kiss it better?

Whenever my toddler hurts himself, I offer to kiss it better. This works like magic—he immediately stops crying and carries on playing happily. Placebos are wonderful things.

Doing this makes me happier, it makes him happier, and also serves as a useful diagnostic tool—if he carries on crying I know he’s actually hurt himself badly.

Teaching children that kisses can make things better is definitely lying to them, but this seems like a good place to make a principled exception. WDYT?
