You think we're kidding? Have a look at the video below and try it for yourself.
It shows three-month-old Seth Dailo fidgeting in his cot before his dad Nathan produces his sleep secret: an ordinary sheet of white tissue paper.
The dad then gently glides the tissue over Seth's face a few times and the baby boy closes his eyes.
By the magic 14th time, Seth has completely drifted off to the Land of Nod.
How come nobody thought of this before?
Nathan, from Sydney, uploaded the video to YouTube, where it has been viewed more than 100,000 times – no doubt by tired parents!
Nathan wrote: "I'm sure every parent tries new things to put their little one to sleep.
"Watch as my wife and I put our 3 month old baby boy, Seth, to sleep in under a minute using nothing but a piece of tissue paper."
One grateful viewer of the video commented: "This worked for my baby five times already so thanks!"
