However, just before announcing that they were expecting their third child, William and Kate were warned not to have any more children.
During a tour of Poland and Germany in the summer of 2017, Kate was reportedly given a baby toy whilst in Warsaw. As George and Charlotte were four and two at the time, she is believed to have said to William: ‘We’ll just have to have more babies!’
Shortly afterwards, children’s organisation ‘Having Kids’ – which promotes a ‘sustainable and child-centred family planning model’ – urged the Duke and Duchess to reconsider expanding their family.
In an open letter, Executive Director President Anne Green Carter Dillard wrote that ‘the example the British Royal Family sets is extremely influential,’ continuing: ‘Your discussion of having a larger family raises compelling issues of sustainability and equity.
‘Large families are not sustainable.’
She added that while George and Charlotte are ‘certain to have wonderful lives… the same can’t be said of every future child.’
Two months later, in September 2017, the couple shared the news that they were expecting their third child and Louis was born in April 2018.
Royal fans have been hoping that a fourth Cambridge baby could be on the way, but during a trip to Northern Ireland earlier this year someone called out to Kate: ‘Number four?’
She replied: ‘I think William would be a little worried!’
Well, that’s that!
