Please never do that thing to any kid or suggest this to any parents...I know earlier this was the method but not now, this world is far more different than those times..she is just five year old kid...Now world is more liberal, have more psychological issues and people are concerned about them..I know as kids we all have tasted one or more slaps but now children are more sensitive...earlier families were big, siblings were more in number and parents were not that attentive to their kids because household chores and financial work was not easy before...But now we live in a different world, problems can't be solved by beating your kid, your neighbours can report you, children can leave home and can be traumatised forever.what she done was wrong like hell and she should be punished but not like you mentioned...I may be wrong but i don't support raising hand on children.
