In common with another well-known British queen, Charlotte had two birthdays this year; her real one last Thursday, and her public one today.
The highlight of this morning's formal duties (think Trooping the Colour) was attending her party at a local play barn. (Can you spot her waving at her subjects?)
There was a big turnout from her bezzie mates (and their dedicated parents).
Even Yoda put in an appearance.
And all seemed to go without a hitch.
Well, I say that. In truth there was one slight hiccup.
You see, three is quite old. And three candles on your cake is a heck of a lot to be expected to blow out on your own.
Enter Oliver Clarke, stage left.
His help was very much appreciated.
