Very calming effect

Got this aa a gift for my little one. It projects a water effect onto the walls and it is quite relaxing to look at. There is also an option to add ocean sounds or lullaby music. My only complaint is that it is only for 20min intervals. My child does not sleep within 20min of putting him in bed. I also wish there was a swnsor that would automatically turn on.the music or ocean sounds when my child wakes at night. But since we got this goft, bedtime has been a little easier so I'm happy.
