Seen this quite a lot in the last few days - mostly on Facebook/twitter etc to be fair. People just really smug that one of their DCs shares a name with the new prince.
Wow, get you - three years ago you picked an already popular name which is now also the name of the future king. They must have copied you, you trendsetter. No no, please show me more photos of your 'Prince George'. 
I've even seen one post where parent was extremely proud of the fact that his DC shared a middle name with new prince George.
I don't get it tbh. And I'm probably being IR.
