TV presenter Beverley Turner – the wife of Olympic gold medallist James Cracknell – said if Kate nursed her newborn on her 'milky bosom' it could help stop the decline of mothers who reject breastfeeding.
Writing in the Daily Telegraph, Beverley said around 5,700 fewer women breastfed their babies in 2012-13, compared to the year before.
"We need women with power and influence to get their milky bosoms out and feed smiling in paparazzi pictures," she said.
"Celebrity is depressingly powerful in dictating trends.
"As if there wasn't enough pressure on her already, what we really need is The Duchess of Cambridge to get her Royal orbs out to feed our future monarch. And to be applauded – not seethed at – for doing so."
The Duchess of Cambridge is said to be due on July 13, but she missed the wedding of her friends Thomas van Straubenzee and Lady Melissa Percy at the weekend and so it has been claimed that Buckingham Palace has kept Kate's real due date a secret and that the royal baby could arrive next week.
In 1982 Princess Diana fooled the public by saying William was due on July 1 – he was actually born 10 days earlier. If Kate, 31, and Wills followed suit, the real due date would be July 3.
