Kate Middleton Pregnant: A Look Back at Famous Royal Baby Portraits (PHOTOS)
Though the royal family are notorious for keeping their family lives private, they do indulge on occasion, releasing portraits of their newest additions. Prince William and Prince Harry's childhood was well documented on film, with their mother -- the late Princess Diana -- even inviting royal photographers inside their Kensington Palace home to snap photos of the boys' everyday lives.
At only five weeks old, in December 1948, the Duke of Edinburgh made his public debut when a portrait of his doting mother, Queen Elizabeth II, overlooking the youngster in his crib was released to the public.
With paparazzi camping out at King Edward VII Hospital, where Middleton is currently staying due to a bout of hyperemesis gravidarum, there's no telling when the Duchess of Cambridge's baby bump will be snapped and released.
Take a look back at famous royal baby portraits in the gallery -- above.
