What's the simplest way to explain proper nouns?

Names get capitals. Your child's own name is the anchor: Mia is a special someone, girl is anyone. From there, pet names, days, and places follow the same pattern. One special thing, one capital letter.

My child capitalizes random words. Is that a problem?

How to teach this

Make it personal: dog is any dog, but your dog has a name, and names get capitals. Sort aloud together and let the capital letter itself be the clue at first; the deeper is-it-one-special-thing test grows naturally out of the sorting.

Watch for: A word isn't proper just because it starts a sentence with a capital. The capital has to belong to the word itself. Days, months, and holidays are proper nouns. School subjects like math are not.
