As part of Jude's Christmas gift I plastered glow-in-the-dark stars of varying sizes all over the ceiling in the nursery. Ladies and Gents, if you are looking for a way to make bed time a time of absolute wonder -- do this.
Jude's eyes were like saucers looking around himself after I
turned off the light. He loves it so, so much. Then when I turned the light back on he was even more amazed, "Where did they go?!" I imagine it'd be extra handy if your little one is afraid of the dark. They give a young mind something to look forward to once the lights are off, rather than just feeling anxious about the darkness.
It's also gives him something to focus on if he wakes during the night. No need to fuss, just fall back to sleep star gazing.
