If you're going for a really unique first name, I think it's nice to give LO a "normal" iykwim middle name, just in case they feel it's too much.
Can work the other way too - I knew a Waldo growing up - Waldo was his middle name, first was Alex. But he always said - I never met another Waldo and loved being unique!!
