Such joy in Prince Harry's face today as he announced the lovely birth of their son.

What a pleasure too that Harry took the moment to send out a shout out to all moms!

And in a first with the son's births, Diana through the Spencer family was finally mentioned.  Here was the Instagram post:

"The Queen, The Duke of Edinburgh, The Prince of Wales, The Duchess of Cornwall, The Duke and Duchess of Cambridge, Lady Jane Fellowes, Lady Sarah McCorquodale, and Earl Spencer have been informed and are delighted with the news," read the family's message.
