Preventing Child abuse

I've often wondered how to introduce the whole idea of child abuse to the twins. As they grow up they're learning to play on their own and there are times I'm not with them... at playdates, birthday parties or even somedays when they're playing down with their friends. I am no longer around 'all the time' like I used to be. And so they need to be taught to look out for themselves.

Here's a video a friend put up on FB. Thought I should share it.
