Prince Harry has said he is determined to make sure his nephew has fun in life - and joked about his babysitting fees.
He is now fourth in line to the throne after the arrival this week of Prince George of Cambridge.
The proud uncle was one of the first family members to meet the Royal baby and said: "When I saw him he was crying his eyes out like all babies do I suppose."
He added: "It's fantastic to have another addition to the family - I only hope my brother knows how expensive my babysitting charges are."
Harry said he was delighted to be an uncle for the first time, and said he wanted to "make sure he has a good upbringing, to keep him out of harm's way and to make sure he has some fun.
"The rest I'll leave to the parents."
He was speaking at an event held at a gallery in central London for his Sentebale charity that works with young children in Lesotho in Africa.
