It was a throwaway comment which had Royal baby watchers whipped into a frenzy of excitement and delight.
On a recent royal tour of Poland , the Duchess of Cambridge joked she and William should have another baby, after being given a present designed for newborns.
Saying thank you for the present, she turned to the Duke laughing and said: “We will just have to have more babies.”
Fans of the Royal family jumped on the royal attempt at banter, speculating joyfully that another little prince or princess could be on the cards.
But not everyone was so thrilled at the prospect of Kate and William adding to their family.
Family planning group Having Kids felt moved to share their thoughts on the subject – which were definitely not in favour of a third child.
The group champion couples having smaller families, and in an open letter to the Cambridges urged them to NOT add to their brood.
“We read with interest your statements about having more children,” the letter begins.
“Our organisation, Having Kids, promotes a sustainable and child-centered family planning model, and we wanted to offer a few thoughts for your consideration.”
Anne Green, Having Kids’ executive director, explained that as one of the world’s most famous families, who many other people look up to, Kate and William should lead by example.
By having fewer children, Green says, the Cambridges would be reducing their environmental impact on factors such as climate change, flooding and wildlife extinction.
“All of us – especially public figures – should plan our families with the future environment in mind, producing a smaller and more resilient populace capable of thriving in that environment,” the letter reads.
The letter continues: “Of course, we know that Prince George and Princess Charlotte are certain to have wonderful lives, protected from the deprivation of poverty and the threat of environmental degradation.
“They will receive optimal amounts of care and attention, as well as the best possible education.
“But the same can’t be said of every future child.”
Cheerleaders for the Royal family were outraged.
“You want to mind your own business! Who are you to dictate how many kids our royals, or anyone has?! Butt out!” wrote on incensed Twitter user.
“We only have one child and live in the UK. Will and Kate can have the rest of the quota allocated by you,” another woman kindly offered before adding, “We don’t live in China!”
Having Kids has since responded to the backlash, explaining they chose William and Kate because of their public stature, and that “the impact the wealthiest families have on the environment dwarfs the impact of children born in the developing world.”
They added that: “given exponential growth, large families – wherever they may be – are simply not sustainable.”
No matter how valid the charity’s argument about over-population and its disastrous impact on the world, it seems there’s no arguing with ardent fans of the Royal family.
But are we really ready for all that hysteria again?
