Lullaby Lamb

Lullaby Lamb is a program designed for Mac that's suitable for children, as well as for grownups, who have trouble going to sleep.

This application plays relaxing melodies in the background and displays a nicely-drawn lamb that's jumping over a pillow repeatedly.

You can use this app in a full-screen or windowed mode and enable the Clock option if necessary (show the time in the center of the screen). In my testing, I almost fell asleep while listening to the background music of this utility.

However, you don't have access to all features. If you unlock the Parents Section (you need to click over a star, circle or square for about 3 seconds), the app suggests making an in-app purchase in order to unlock all features. Nevertheless, the acquiring price is affordable.

After you make the in-app purchase, you will be able to choose between 10 melodies (instead of one in the trial version), select the amount of time to play the songs, etc.

In conclusion, it's worth installing this program on your Mac only if you plan on purchasing the full version with all the features included.
