Kate Middleton will make a public appearance in London on Sept. 17. The Duchess of Cambridge will visit the Anna Freud Centre in the city to see their work in children’s mental health care.

Kensington Palace announced the official engagement of the mother-of-two on its Twitter account on Friday. “The Duchess to visit the Anna Freud Centre @afcevents on 17 Sept to see their work in children's mental health care,” the tweet said.

The London-based Anna Freud Centre is a clinical, educational and research institution specialising in the psychological treatment of children and young people, Hello reported.

Middleton who is spending some time off with her two children Prince George and Princess Charlotte is a patron to various children’s charities providing help and assistance for young children. She is patron of East Anglia Children’s Hospices and The Art Room, as well as working with Place2Be and the Scout Association.

The 33-year-old royal has been out of the media glare since she gave birth to Charlotte on May 2. She last attended an official engagement with her husband Prince William for a sailing event at the America’s Cup World Series in Portsmouth in July.

Kate released a statement in March to mark the Time to Mind campaign, a project that was set up by The Times for greater investment in children and young people’s mental health. She also recorded a message for Place2Be, of which she is a royal patron since 2013.

Meanwhile, the family-of-four is reportedly set to join the celebration to mark Queen Elizabeth II’s 63 years on the British throne. The couple along with their two kids will celebrate Elizabeth’s record at Balmoral castle on Sept. 9.

A senior royal source told that William and Kate will make an official overseas visit in the New Year. Fans of the royal family were disappointed by the news that baby Charlotte and her big brother Prince George would most likely not be joining their parents on the trip in 2016.
