Prince William gave a little bit away about his young son in a documentary due to be screened on Sunday.
The 31-year-old laughed off questions about Prince George's legacy and said:
"At the moment, the only legacy I want to pass on to him is to sleep more and maybe not to have to change his nappy quite so many times, but as he gets older I'm sure he'll pick up the bug of conservation."
