My one year old can't talk yet. The poor little guy is currently sick, and yesterday he was sitting on the floor, rolling his head forward and moaning "OOooooohhhh", over and over.
I moved to comfort my poor ailing son when he suddenly clapped a few times, then started the moaning again, then clapped again.
It took a few moments more to realise that, a little while before, the stereo had been playing the hokey pokey.
Ooooooh, the hokey pokey.
That's what it's all about.
