The wise Jedi master Yoda could not have done it better - the theme music from Star Wars has 'magical abilities' to calm a screaming baby.
A video posted on YouTube shows a mobile phone playing the distinctive theme tune being placed next to a crying, agitated four-month old in his cot. He relaxes within seconds.
YouTube user SebastianL2012, from the US, explained: 'We discovered by accident that the Star Wars Theme Song has magical abilities to calm the baby down.
'He was screaming and crying in the car one day, and the MP3 player started playing this song and he just stopped.
'Then, every time after that when he'd be crying for no reason (we knew his diaper was clean, tummy was full, etc.) and we'd play this song, he'd perk right up.'
The video has racked up almost one million views on YouTube in just a matter of days, and thousands of 'likes'.
One user wrote: 'May the force be with him.' Another added: 'He will be a good a Jedi.'
