Name the practical limit honestly
If you are tired of reading a long book every night, say what you can offer: one section, alternating nights, or a shorter choice tonight. Avoid inventing a claim that the book is unavailable when it is on the shelf. The child may value a particular scene, phrase, or character, so ask which part they most want to hear. That can help you choose a manageable version of the session without assuming you know why the repetition matters.
Invite another book through a real connection
Offer a new story with a feature the child already likes, such as a similar setting or a funny refrain. Let them look at the cover and a few pages before deciding. Keep the familiar choice available within the agreed routine. Do not present trying something new as a test of being a better reader or becoming more grown up. The invitation can be modest: one new page alongside the familiar book is still a new experience if the child wants it.
Make shared choices fair
If siblings participate, rotate who chooses or agree on one short selection each when time permits. Explain the rotation before opening the books. A child can be disappointed about another person’s turn without losing their own future choice. Revisit the arrangement if the combined session is too long. The family can enjoy a favorite and protect the adult’s or sibling’s preferences at the same time, without turning a reading ritual into a daily argument about novelty.
