The Duchess of Cambridge will visit Cardiff on a 24-hour UK tour as she launches a survey on early childhood.
Kate hopes the survey will spark conversation that will encourage “positive, lasting change for generations to come.”
She has already travelled to Birmingham as part of the launch, and will also make stops in London and Surrey.
While in Cardiff, the Duchess will visit a children’s centre in Ely.
The survey was conducted as part of Kate’s work for The Royal Foundation.
The Foundation said the public feedback will help Kate on her endeavours to provide children across the UK with the best foundations for leading healthy and fulfilling lives.
On Tuesday she visited a science museum in Birmingham, where she met with children, parents and carers.
Kate’s last trip to Wales was in May last year. She and William travelled to North Wales – where they used to live after they were first married – to meet search and rescue pilots.
When the Duchess arrived in Birmingham she said: “I’m here today to help launch a survey to hear society’s views about raising the next generation.
“Parents, carers and families are at the heart of caring for children in the formative years, so that is why I want to listen to them.
“As a parent I know how much we cherish the future health and happiness of our children.
“My ambition is to provide a lasting change for generations to come.”
The Duchess’s survey will run for a month, from January 21 to February 21, and will ask those taking the poll five questions to gauge their views about early years.
