Although I was not a parent, but I think this video from King of fairy tales Zheng Yuanjie is very meaningful.
Mr Zheng use Vampire and Pipilu to teach children to prevent sexual assault.
And the law he noticed is China’s Law. But it is similar with other countries.
This is a video from Zheng Yuanjie Blog
