Out of interest, does anyone ever use their middle name? Our three have them, but aside from their birth certificates, I don't think I've ever used them since! We gave them fairly traditional middle names in case they decided to use that instead as adults - Rose, George and James as opposed to Sophia, Flynn and Henry.
I can remember a lad at school used his middle name instead of his first name, and his older brother did the same thing, so they ended up with each other's names. They were James Tim and Tim James respectively...confusing!
My grandad was called John Christoper and his brother was called Christopher John and confusingly, my grandad went by the name of Christoper
