Speaking to Express.co.uk, motherhood expert and founder of Bloom baby classes, Victoria Jennings said: “As a mum of three, I completely understand how it looks as if Prince Louis is Kate Middleton’s favourite child.
“As a parent, things go by in a flash and so you want to nurture the youngest child for as long as possible,” she told the publication.
Like many parents, the Duke and Duchess are enjoying their youngest child's baby years for as long as they can - but this could also be a sign Kate won’t have any more children.
“You just want to baby the third child for as long as possible, especially if you’re thinking they will be your last,” Victoria said.
The Duke and Duchess regularly share family photos to their Instagram account.
Last month, they visited the Chelsea Flower Show the RHS Back to Nature Garden, which was designed by Duchess Kate.
Proving that family is front of mind for Kate, she created the garden as a woodland setting to show how families can come together to enjoy nature.
