Imagine you have a little lighthouse in your crib, just like the ones you see at the beach. This lighthouse has a light on top that spins around, just like the real ones.
Now, let's say you're asleep in your crib, and it's dark in your room. The lighthouse light starts spinning around and shining bright light everywhere, just like a nightlight. It helps you feel less scared in the dark because you can see everything around you.
The cool thing about this lighthouse is that it's designed specifically for babies. It's safe, and it won't get too hot or bright. It's also battery-powered, so you don't need to plug it in anywhere.
So, in short, a crib lighthouse is a nightlight designed to look like a lighthouse that shines a soft and safe light in your crib to help you sleep better and feel less scared in the dark.
