Kate Middleton fueled rumours that she and Prince William are hoping for baby number four while dancing with a baby at the RHS Garden Wisley.
Following her entrance to the event via tractor with British TV personality Mary Berry, the Duchess of Cambridge got in touch with her maternal side as she played with children at the Back to Nature garden launch.
Wearing a floral dress by Emilia Wickstead, the mother-of-three was seen laughing and dancing with a small baby.
A local Australian publication reported that she told the child's mother that her son Prince Louis loves to "smell flowers in the garden."
Kate also spoke to families who were invited from the Evelina London Children's hospital - one of the royal's patronages - as she planted a blue cedar tree at the RHS Garden Wisley's new space for families.

Expressreported that the garden will have a 'bouncing forest' of trampolines surrounded by trees and a living willow pod.
The Duchess collaborated on the design of the garden with the Royal Horticultural Society and Davies White Landscape Architects.
"The Back to Nature festival is a fitting finale to a project I have been thrilled to be part of," Kate said at the event, according to the publication.
"It has been the most amazing experience and I can’t thank the RHS enough for giving me this wonderful opportunity.
"I hope that it will enable thousands of children to discover and explore the natural world around them."
Other new features included a treehouse and a hedgehog-inspired shape for children to enjoy.
"I am not as green-fingered as many of you here, but I was passionate about creating a garden that inspired children and adults alike to get back to nature and reap the positive mental and physical health benefits that it can bring," she added.

The Wisley garden is located in Surrey and is one of five gardens run by the Royal Horticultural Society.
"RHS Garden Wisley is our flagship garden, welcoming over a million visitors a year, many of whom are families with young children, who we want to become the next generation of gardeners," said Sue Biggs, RHS Director-General.
"How magical for these children to play somewhere that has been inspired by gardens co-designed by The Duchess.
"We are grateful to The Duchess for the incredible impact that this ‘Back to Nature’ collaboration has had.
"There is no doubt that this project, through her passion and vision, has highlighted that access to natural environments and green spaces isn’t just a nice to have, it’s vital to have. This is something that the RHS also strongly believes in and will continue to champion through our Greening Great Britain Campaign and charitable work."
