When I first hung these on the wall and my one year old saw them she started to laugh. Now when shes getting ready to lay down in her crib we go in and turn these on, and say good night to them and she laughs.
These are pretty good lights that offer some light but aren't overly bright. The not to bright light is nice because it allows my daughter to relax and not go into awake mode. They take batteries, double A's and we have left them on overnight five or six nights now and the batteries are still going at this time
