Before he was known as Prince George Alexander Louis everyone simply referred to him as the royal baby but now it looks like the little guy has a fun childhood to look forward to with uncle, Prince Harry, vowing to teach his nephew how to have fun.

The royal joked around on Thursday night about how expensive babysitting skills with cost his brother while attending a private viewing of an exhibition at The Getty Gallery in London.

The 28-year old helicopter pilot went to go see his brother, the Duchess of Cambridge and their baby Prince George shortly after the family returned from St. Mary's Hospital on Tuesday night, according to the Daily Mail.

Making hand gestures as he spoke to the media, Prince Harry described the child as being "about this long and that wide."

"When I saw him he was crying, which is just like all babies," he said describing his visit to Kensington Palace.

"It's fantastic to have another addition to the family."

He also said, "I only hope my brother knows how expensive my baby sitting charges are!"

The royal was ambushed with question about his nephew with one reporting asking him who the baby resembles more to which the Prince said it was much too early to tell seeing as the child is only 4 days old.

But as an uncle he feels as if his duties to the third heir to the throne require him, "to make sure he has a good upbringing and to keep him out of harm's way and make sure he has fun.

"'The rest of it I'll leave to the parents."

The Daily Mail reported that Prince Harry also insisted that Prince William was going to be a good father, when asked if his brother's apparent confidence with the baby car seat outside St. Mary's Hospital on Tuesday indicated he was cut out to be a good father, he said "Of course he is!"

The royal was attending the launch of an exhibition by photographer Chris Jackson which highlighted the work of his charity, Sentebale. Back in 2006 Prince Harry co-founded the charity in memory of his late mother, Diana, Princess of Wales.

According to the Daily Mail, its mission is to help children in Lesotho, a poverty-stricken African kingdom affected by HIV and Aids. The country has the third highest HIV/Aids rate in the world, despite being one of the smallest kingdoms. Almost one in four of the population is infected.
