Change a story feature and explain the new meaning.
My own try
Read the whole different source
A toy train story starts with the train wanting to explore. It follows a drawn track to a paper station. A friend hangs an Adventure sign there. The train decides that the station can be the beginning of a new story and stops beside the sign.
Adult reads the whole source neutrally when wanted; exact child-directed recording, pointing/sign/AAC/drawing/type/speech remain available. Match print separately; no voice/neatness/speed gate.
