Children who like to read usually grew up around books that people actually enjoyed. A quiz at the kitchen table is a weak substitute. Let them see you read. Mention a story at dinner. Leave a few books where they sit, not only on a high shelf.
A library visit still helps, and a free ebook is an easy yes when they get curious. Comics, joke books, and dinosaur facts count. They do not have to be classics to grow a reader.
Ask something they can play with. "Which character would you invite over?" lands better than a question about page four. Reading with a sibling, a grandparent on a video call, or a classmate makes the habit feel social.
A short stretch on most days beats one long session on Sunday. You are trying to make them want to come back.
