Sorry but i am not having my 11 year old get her ears pierced and look like a clown in public with the big bird yellow hair.
They can and should express themselves but they are still a kid and this is a bit extreme.
Now this is cute
And if they want to shave their heads fine. I think the people commenting are saying that while kids should have their own identity letting them do whatever they want at such a young age is not a good idea.
It will bite you in the ass later.
