I'd be expecting to see a big slobbering dog come bounding round the corner if I heard someone calling out "Prince" (unless baby is Black African) sorry. Have you said it out loud with the surname he will have, or tried saying out loud - ie here is Prince Caspian, or Prince McNuggets, or can I register my son Prince McPrinceFace at this dental practice please? You will need to be prepared for your son having to learn very quickly how to spell both his first and surname (& any other middle names he might be called) and to patiently explain, yes that's my name, yes I know what it means, no I am not a prince of royal birth, no, I am not related to the Queen, yes my parents love and wanted me ...…. and the merciless teasing he will get all through school and so on. I know - I was "gifted" with a really unusual forename, please don't put him through it.
