In this instance it's a bit unfair to the child as they're clearly not thinking ahead. But is this generally considered a bad thing? Only recently I discovered my son's friend's name wasn't his birth name at all but a nickname based on his favourite drink as a toddler. He has never been known by his birth name so deed poll might be appropriate for him.
What do others think?
