The Duchess of Cambridge has attended her first solo public engagement since the birth of Princess Charlotte.
ITV News Royal Editor Tim Ewart reports.
Kate visited a children's centre in London on her first day back at work.
The centre treats young people with mental health issues and works on developing new treatments and approaches.
Wearing a dogtooth dress and showing of a new fringed hairdo, the Duchess looked in fine form as she greeted staff.
She chatted to parents and children as she was shown around and looked happy to be back at work.
It is four months since her second child Charlotte, little sister to Prince George, was born on May 2.
The centre is named after Anna Freud, a pioneer of child psychoanalysis and a daughter of the famous psychoanalyst Sigmund Freud, who was instrumental in its creation.
The Duchess also visited the centre's family school, which opened in September last year, and provides alternative education for youngsters who are seriously at risk of exclusion and are struggling to achieve.
