Zara Phillips and Mike Tindall introduce relaxed and happy baby Mia
The royal couple have sold the first pictures of their baby daughter Mia to Hello! magazine.
Buckingham Palace declined to comment on whether the Queen had been consulted over the photographs, which appear across 13 pages of the glossy magazine.
Olympic medal winning sportswoman Zara and former England rugby star Tindall revealed that their daughter was "pretty relaxed and happy so far".
The couple said they hired a maternity nurse for the first few days to help them get to grips with parenthood.
Mia, whose name was announced by her father via Twitter, was born in the NHS at the Gloucestershire Royal Hospital.
"We'd never even contemplated going privately," the couple told the magazine.
Mia's second cousin Prince George - a future king - was born at the private Lindo Wing of St Mary's Hospital in Paddington, London.
Zara also disclosed that she had an epidural. She said she was hoping to resume her equestrian career and enter the Burghley Horse Trials in September but for now they were "taking each day as it comes".
Tindall, who was described by his wife as a hands on father, said: "I still keeping looking at Mia and thinking 'Oh! We made that!'"
The Queen's fourth great grandchild, who is 16th in line to the throne and was born on January 17, appears on the front cover of this week's edition.
Dressed in a white striped baby gro, Mia, awake and content, is pictured lying in front of her proud parents.
In 2008, Zara's brother Peter Phillips was criticised after selling photos of his wedding to Canadian bride Autumn Kelly to Hello! and reportedly receiving £500,000 in return.
At the time Liberal Democrat MP Norman Lamb described the move ''a serious error of judgment'' that "smacks rather of greed".
Last September, Prince and Princess Michael of Kent's son Lord Frederick Windsor and his wife Sophie Winkleman posed for Hello! with their baby daughter Maud.
Earlier this month, Hello! published paparazzi photographs of Prince George in the arms of his mother the Duchess of Cambridge as they left a British Airways plane while on a Caribbean holiday.
Some commentators expressed surprised that the Cambridges had apparently not tried to stop the publication of the paparazzi images.
A spokesman for Hello! magazine said: "We are delighted that Zara and Mike Tindall chose to share their beautiful baby pictures with Hello!"
