@ Royal Shiny : a 'normal childhood' would mean 'having a normal childhood living' - away from being supervised or dictated by someone, away from being stopped from doing childhood things and to experience the precious childhood life.
I believe this is one among the frustration of Michael Jackson. hence, written the song "Have you seen my Childhood."
Children, despite of being a 'telented', should ALWAYS be given the privelege to experience their childhood the way it is. This is the most important stage in life where they can be developed not just by their parent's guidance alone, but by themselves.
