“I don’t know — let’s find out”

Most of a child’s questions are ones no grown-up can answer on the spot. That is normal, and it is useful: it lets you show how a person finds something out.

Saying you don’t know is not the end. Name a way to find out — a book, a library, someone who works with it, a test you can try at the table — and do it together, or write the question down so it can wait.
