Royal fans think Prince Harry has changed in a BIG way since becoming a father.

As you may be aware, Meghan Markle and Prince Harry welcomed their firstborn into the world on Monday morning and baby Archie has been the centre of attention since. At only two days old, he was unveiled to the world alongside his beaming parents and of course, the announcement of his name, Archie Harrison Mountbatten-Windsor, was the subject of much chat too. However, the Duke and Duchess of Sussex are also getting lots of attention from their many adoring fans. A number of people pointed out that there's been a significant change in Prince Harry since becoming a dad. As pointed out by The Express, fans shared their thoughts on the Sussex Royal Instagram page, the official account dedicated to the family. Although Prince Harry generally has an amenable demeanour, he literally can't stop smiling since Archie arrived and is besotted with his little boy. It's really rather lovely and we have to agree with them as he's the picture of happiness in these new photos. One said:

"Harry is radiating new father joy, his face is adorable as he received the onesie".

Another commented on his smile and remarked that it's such a change.

"Haven’t seen him smile like that since he was a child. He’s got the bond and love for his son that his mother had for her boys. It’s wonderful to see".

Most people had the exact same reaction, that his joy at being a father is evident for all to see and he's never looked happier.

"His face with the onesie. Meghan and Harry seem so happy and blessed!! Here’s to them and the future they help curate!"

So adorable, huge congrats to the new parents.
