It's been a busy old week for Archie Harrison Mountbatten-Windsor.
Not only has he finally been able to meet Prince Charles , his grandfather, the Duke and Duchess of Cambridge also swung by Frogmore Cottage on Tuesday.
Sadly he'll have to wait a little longer for cuddles with his older cousins, as William and Kate's visit took place after George, Charlotte and Louis' bedtime.
These introductions come hot on the heels of Prince Harry's aunt, Lady Jane Fellowes, being one of the first to see the Sussexes as a family of three.
Of course, there is one very important person whom Archie will tragically never have the pleasure of knowing.

"In a quiet moment away from all the hoi-polloi and the fuss he will sit down and one of his big regrets will be that he never had an opportunity to show his mum how proud he is of his new son.
"Unfortunately that's something Harry’s had to live with since he was 12."
However, Mr Larcombe believes some good will emerge from Diana no longer being here.
He added: "We've got to remember for people who have lost their parents in childhood it gives extra significance once they've become parents themselves.
