A baby bedtime book should end on a picture of someone asleep, or on a hug. If the last page invites a game, you will be reading it twice and nobody will be closer to sleep.
Goodnight Gorilla and Kiss Good Night do this well. The Napping House builds a pile of sleepers and then wakes them, so read it early in the routine, not as the final book. Pajama Time! and Snuggle Puppy! are the wiggly ones. Use them while pajamas are going on, then switch to the quieter story.
Ten Minutes till Bedtime is funny about stalling. A toddler who is already stalling may not need the idea. Save it for a night when the joke will help instead of adding another delay.
Same book, same chair, most nights. At this age the repetition is the routine.
Sit in the same chair. Use the same voice. A baby does not need a new plot every night, and a book they already know is easier to fall asleep inside.
