Find out what animals sleep during the day and are awake at night. Choose some animals to pantomime while they are asleep. Decorate boxes like little beds for their stuffed animals. Talk about the different ways everyone gets ready for bed. Have on hand some of the things children might use when getting ready for bed.
Some suggestions are a toothbrush, toothpaste, washcloth, soap, book, glass of water and blanket.
Ask the children to recall and share their bedtime routines. Use the props to act them out. This is a good activity for sequencing. Goodnight Moon Read story, flannel board re-telling and then set up Goodnight Moon Room with all the objects set up like the book. Have children bring flashlights to school and as you re-tell the story have them shine flashlights on the objects.
