If you’ve tried everything and nothing has worked, don’t give up just yet. Simply reach for the Kleenex.

In under a minute, YouTuber and Australian father Nathan Dailo sends his baby to sleep by gently tickling the infant’s face with tissue paper.

“The tissue trick isn’t actually anything special. Any light touching on the baby’s facial areas such as the head, forehead or the bridge of the nose also works,” Dailo tells TIME.

The video has garnered more than 4 million views and inspired innumerable other parents to deploy the technique. However, Dailo cautions that his technique isn’t the only one.

“Remember that each child is different, and what works for some parents may not work for others. And always use you’re instincts. You are the parent,” Dailo stresses.
