for children under 5?
Alexander or Alexandra...but go by Alex rather than Xander/Sasha/Sandra/Lexi etc.
I keep hearing and reading it's been done to death/very common in the UK at the moment but other than one 10 year old who lives abroad I don't know a single one under the age of 30. Not one in our local primary school for example. Friend who is a nursery worker hasn't seen one in years either.
