There is no one right way to parent a child beyond the basics of love and boundaries. Children are born with different temperaments and ways of responding to the world and what works for one child is wrong for another. Most children are resilient and will bounce back but there are a few who are particularly vulnerable to addictions, psychological disorders and extreme behaviour.

That emotion can certainly be feisty independence, but it doesn't mean it has to be, and songs and artists shouldn't be left off the list because they don't fit this dubious criteria.
