If you've ever struggled to get a baby to agree to nap, you'll be envious of this woman's apparently magical sleep-inducing powers.
The clip was posted to Facebook by French magazine Pour Nous Les Femmes back in November - and it's been shared more than 65,000 times, picking up more than 3 million views.
This woman's technique essentially involves gently stroking the baby's head and face with her fingertips - and it seems to work a treat. The infant does indeed go from apparently wide awake to full sleep in under a minute, despite being in a room full of cooing grown ups.
Comment faire dormir un bébé en moins d'une minute ... :)Posted by Pour nous les femmes on Sunday, 11 October 2015
Another video purporting to show you how to send a baby to sleep in less than a minute also went viral recently.
Sydney dad Nathan Dailo uplaoded a clip of him getting baby boy Seth to sleep using nothing but a tissue.
Dailo strokes Seth's face repeatedly, and very gently, with the tissue: in a mere 42 seconds, the baby goes from a ball of energy to a sleeping cherub.
In yet another viral clip, a doctor demonstrated how to calm a crying baby quickly and easily.
In the clip, Dr Robert Hamilton of Pacific Ocean Pediatrics in California demonstrates a technique called 'The Hold'.
The technique involves folding a baby's arms together in front of his or her chest, then supporting its bottom with your dominant hand. Keeping the baby at a 45-degree angle, you then wiggle his or her bottom backwards and forwards.
"Everything you do is very gentle," says Dr Hamilton in the video. "You don't want to do jerky motions, ever."
The YouTube description says: "This technique has been utilized by Dr Bob to quiet infants during office visits. Parents have learned it and have experienced great success at home. You can too."
CBC News spoke to Christine Chambers, professor of pediatrics at Dalhousie University in Halifax, about the incredibly popular clip.
"The video shows a variant of a newborn care strategy called facilitated tucking." she said, Facilitated tucking, in which the baby is also held in a flexed position, typically takes place in a crib or incubator rather than in the air.
According to Chambers, the babies in the video may be reacting to the novelty of the experience - and, unfortunately, the calm isn't likely to last.
However, for parents at the end of their tether, it's got to be worth a try.
