This is the hilarious moment a crying baby instantly calms down after his mother brings out a head scratcher to entertain him.
Filmed in the US, the baby looks ecstatic as his mother rubs his scalp with the device.
He is lying on a bed crying at the start of the video, kicking his legs in frustration.
His mother, Courtney White, brings a head scratcher into view, catching her baby's attention instantly.
As she twirls the device around, her son laughs in delight, following excitedly with his eyes.
He laughs happily as the device comes closer to his head.
Adorably, the baby screws up his face in joy as the head scratcher gets to work.
He giggles, body squirming in ecstasy as the device, controlled by his mother, gently presses into his head.
The video was viewed more than five million times on Facebook after mother Courtney uploaded it.
