A bedtime story works best when it happens the same way most nights. Children settle faster, they hear more words, and the book becomes something they expect.
Pick one cue and keep it. Lights down, teeth brushed, then a book. Ten or fifteen minutes is enough for a toddler or a new reader. Offer two titles and let them choose. That small choice usually ends the hunt through the whole shelf.
Keep the gentle picture books for the pillow. Adventure and long chapters can wait until earlier in the evening, when nobody is trying to fall asleep. If your child is still wiggly, slow your voice and look at the pictures together.
A few free ebooks from Apple Books or Amazon are enough to rotate stories without a new hardcover every week. Miss a night, then start again the next one. The habit comes from coming back.
After a few weeks, many children start asking for book time on their own. That is the part worth keeping.
