I think that you should be allowed to call a child, more or less anything you want and spell it however you want (obviously, within reason so that it's not an abusive term - not 'Oy' or 'Blockhead' etc.)

But I also think that a child should be able to reregister their name officially at a certain age. So that if they have been called 'Moonbeam' or even just a different spelling of their own name they can change it officially at a specific age.
