The Queen met with William and Kate and enjoyed seeing several royal children as she continued her recovery from Covid, it is reported.
The Cambridges were said to have met with the monarch as they look for a new school for Prince George in Berkshire where he is expected to start in September.
The Queen saw the Cambridge’s three children as well as Princess Beatrice and her daughter Sienna at Frogmore Cottage on her Windsor Estate last Sunday.
She tested positive for Covid last week after the virus was passed around the Royal Family and this was an opportunity to see people again as she makes a “good recovery”.
Princess Eugenie and her husband Jack Brooksbank currently live at Frogmore Cottage but they are not thought to have been at home to see the monarch.
The Queen suffered health concerns at the end of last year when she had to cancel royal engagements and last week she was unable to attend others due to being in isolation.
The trip by the Cambridges to see the Queen coincided with their search in Windsor for a new home after viewing suitable property.
They are expected to live in the Royal Borough at weekends and holidays.
The Windsor location is near Kate's family home in Bucklebury where her mum and dad Michael and Carole Middleton enjoy being hands-on grandparents.
Royal watchers say the couple's weekday base will, however, remain Kensington Palace.
Anmer Hall, their Norfolk home, could then return to the Queen to pass on or rent out privately.
William and Kate are now mapping out where they want to settle down as a family.
But it could be 20 years before the couple progress to the throne and they are keen to give their children as normal childhoods as possible before that.
They royal couple have a comfortable home-office arrangement at Kensington Palace and are said to be conscious of the £4.5 million cost to taxpayers of improving their 20-room apartment
George will be nine in July, but Kate and William believe he should move to an out-of-town school with facilities on campus.
Schools, either weekly or 'flexi' boarding are reported to be being considered.
