The royal - who wed the newly titled Duke of Cambridge in a lavish ceremony at London's Westminster Abbey last Friday - will not be undertaking public engagements alone for the foreseeable future and has chosen to stay at the couple's rented farmhouse in Anglesey, Wales, while William works as a search-and-rescue pilot.
The only events in her calendar include watching Prince William play in a number of polo matches and the Duke of Edinburgh's 90th birthday.
A source said: "The couple will do things as a pair after their marriage and for the foreseeable future. Catherine will not be conducting any solo engagements. The number of engagements she does with William will remain pretty level.
"Prince William has a full-time job he has to work round and that is his priority. He is committed to it for at least another two years so nothing much will change in the immediate future, apart from the fact that he and Catherine will take part in the queen's Diamond Jubilee celebrations next year."
However, she is expected to eventually undertake her own royal duties and support charities separately from the duke.
The source added to Britain's Daily Mail: "She will, in time, become associated with her own charities but this won't happen immediately as she wants to explore the fields that interest her first."
