The Windsor Family Hub is run by Achieving for Children, a non-profit which provides children's services across the Royal Borough of Windsor and Maidenhead.
Its services support children, parents and carers through its family hubs, with both universal and more tailored help available.
While visiting the hub today, Kate is spending time with a number of different groups who are currently making use of its services.
These include people taking part in a stress management course, health visitor sessions and baby massaging.
The Princess's Shaping Us campaign, which was launched at the beginning of the year through the The Royal Foundation Centre for Early Childhood, aims to improve the lives of young people by focusing on enhancing their earliest experiences.
