The Duchess of Cambridge is joining Christmas celebrations at a leading centre for youngsters with mental health issues.
Kate will take part in festive activities with children and their families at London's Anna Freud Centre.
The Duchess visited the institution in October to learn about its work and development plans for the future.
The centre is named after the pioneer of child psychoanalysis - and daughter of the famous psychoanalyst Sigmund Freud - who was instrumental in its creation.
She set up the Hampstead War Nurseries in 1941 in response to the social and emotional upheaval faced by children in wartime, and over the decades it developed into a centre of teaching and research and a major service provider.
Kate will join family groups working together at tables to create a Christmas tree collage.
The activity is part of an end-of-term reflection, with parents helping the children remember the progress they have made, both academically and in social relationships.
Children, parents and staff will then give a performance to celebrate the end of term and Christmas, demonstrating the skills they are developing in drumming workshops.
