The Princess of Wales is not expected to return to public duties until after Easter as she recovers from major abdominal surgery - and Prince William will complete the school run.
Catherine was admitted to The London Clinic on Tuesday and is likely to remain in hospital for the next week. But when she returns home, she will likely complete some admin work and keep in touch with charities and her Shaping Us campaign, the Telegraph has said.
“Her commitment to Shaping Us and the early years will continue,” a source said.
The Palace has refused to confirm what Kate was being treated for but confirmed the condition was non-cancerous.
King Charles has also been experiencing health issues and has confirmed he will need to undergo surgery for an enlarged prostate.
While the Queen steps up to cover appointments, William is set to step up his dad duty - with his wife understood to take their three children to school. It was recently revealed that the reason she did not travel to Balmoral as the Queen died was because she wanted to look after George, Charlotte and Louie.
Catherine is close to her family, and her parents Carole and Michael Middleton and siblings Pippa Matthews and James Middleton are set to rally round and help support her recovery at the Waleses' home in Windsor.
The couple are thought to have delayed their official visit to Italy in March.
Kensington Palace has reportedly rescheduled engagements with Catherine’s 30 charities and patronages.
An aide added: “Her passion for the early years is clear. There will be a huge continuation of that campaign and she will be keen to continue that conversation with the nation as soon as possible.”
