Parents, if you want to stop tantrums and sulking in its track, there's a small but extremely effective trade-off (warning: you may actually prefer the sulking option).
Simply buy your little one the noisiest and most annoying pair of kids' shoes ever, and watch their troubles melt away to a soundtrack of ear-grating squeaks.
That's exactly what happened to fun-loving tot Yerin, who quickly discovered it's hard to stay angry when you're wearing squeaky shoes. The footage from Korea showing the little girl grumpily ignoring her father before erupting into a fit of giggles over her noisy footwear has had over a million hits in just one month.
