YouTube user Useless Duck Company noticed that his friends were having lots of babies. He wanted to offer them a gift that was both unique and practical. The result of his efforts was an automatic baby soother. The whole thing is controlled by an app that you can load on a phone.
When the baby wakes up in the middle of the night, press the music button. That activates music from a speaker in your baby's bedroom. If that doesn't work, press the rocking button. A pneumatic piston rocks the baby's crib until he stops crying.
Be sure to watch until the end of the video.
