HOW much do children in the middle of a tantrum hate being mocked?
Who hasn't had 'don't laugh at me!' bellowed at them by a red-faced and irate toddler in the midst of a meltdown?
And given how badly little ones react to laughter when they are crying, wailing and in the midst of a total paddy, this video shows one VERY brave dad having a giggle at his little girl's expense!
The 40-year-old was filmed by his wife, Kathy Sterner, who uploaded the hilarious clip to YouTube.
Kathy explained that their little girl had been screaming the same thing over and over for an hour, and her dad was able to anticipate what was going to come next - resulting in the very funny video.
"My six-year-old daughter had been in her room wigging out for about an hour, and there was no talking her down," she said. "I was getting fed up, so my husband decided to lighten the mood."
"We could hear her take a breath when she was about to start up again," she said. "The 'Stop laughing at me!' was a new and unexpected twist, and he went with it. He's a pretty good actor, and was big into improv when he was younger."
Brilliant! (or cruel?)
