Kate Middleton spent her ninth wedding anniversary supporting charities working with pregnant women and new mothers.

The Duchess of Cambridge, 38, and her husband, Prince William, 37, got married at Westminster Abbey on 29 April in a service that was watched across the globe.

Last week the couple marked nine years of marriage but were forced to stay home due to the ongoing lockdown.

And according to the Court Circular – the official daily list of royal engagements – the duchess spent the afternoon taking part in a roundtable discussion with organisations supporting women in her role as patron of the Royal Foundation of The Duke and Duchess of Cambridge.

It is understood the Cambridges are isolating at their Norfolk home, Amner Hall with their children Princess Charlotte, 4, Prince George, 6, and Prince Louis aged 2.

The duchess is thought to have a passion for parenting, having launched a series of initiatives aimed at studying early childhood.

She launched a survey titled “Five big questions on the under fives” which gave Britons a chance to offer their views on raising the next generation in January

The survey comprised five short questions designed to help shape public perceptions of the importance of the early years through first-hand experiences as offered by parents, families and carers.

The duchess then travelled to Birmingham, Cardiff, Surrey and London in just 24 hours to help collate the responses.

During lockdown, the couple has been using video calls to support charities, talk about mental health, schools and the NHS.

Last week, the Cambridges made a surprise TV appearance on the BBC’s Big night In to join the nation in applauding frontline workers during the coronavirus pandemic.

Prince William will also appear in a new documentary addressing mental health as part of the BBC’s Mental Health Awareness Week.

With a working title of “Tackling Mental Health with the Duke of Cambridge“, the film sees Prince William discuss “men’s mental health through the prism of football.”

Other new films include What’s The Matter With Tony Slattery, in which the comic seeks answers to his mental health problems.

The series will also feature previously aired documentaries such as Rio Ferdinand: Being Mum And Dad, Alastair Campbell: Depression And Me, Killed By My Debt, and Nadiya: Anxiety And Me.

Announcing the series, which will run throughout May, BBC director-general Lord Tony Hall said it was “more important than ever” to raise awareness of mental health issues.

He added: “Mental health is important and, during this pandemic, more important than ever. Many people may be struggling alone, be worried about maintaining their own well-being, or want to better equip themselves to help loved ones.

“That’s why bringing mental health issues out into the open is so important. Our programmes aim to do just that. They highlight the issues affecting many and will hopefully help people seek the support they need.”
