Children have a language of their very own

I rarely post videos of children on here that aren't my own kids because, well, obviously my two are the most adorable in the whole wide world.
But I stumbled on this video and it just had me mesmerised.
We all know kids have their own language and that they get hugely frustrated when no one else can understand it.
However, if you have a twin brother . . .
Enjoy x
