They added that Kate helps keep the family “down to earth”. Born into a middle-class family and educated in public schools, Kate experienced a childhood far removed from the royal spotlight.

Kate, also an avid advocate for the benefits of nature on mental health, has previously shown she frequently takes her children on nature walks and encourages them to explore the world around them.

It is said the mother of three will make the journey to Scotland this summer so her family can spend time with King Charles and Queen Camilla at Balmoral.

Princess Kate also has a helpful support network around her including her mother Carole Middleton, the insider said, which has proven to be a sign of strength following her cancer diagnosis earlier in the year.

The source added: “She has a lovely supportive family to turn to, which helps.”

As Kate undergoes treatment following her diagnosis earlier this year, she has relied upon her immediate family in her time of need. Carole, 69, is known to be very close with her eldest daughter, and was branded a “real Mary Poppins-like figure” to her grandchildren Prince George, Princess Charlotte, and Prince Louis.

A source previously told the Independent: “Carole has been the driving force keeping the family together with minimum fuss and maximum modesty. She’s ferried and fetched George, Louis and Charlotte, taken them to school sports matches and given them endless support. She’s been a real Mary Poppins-like figure.”

Royal expert Jennie Bond also told the Mirror: “Catherine may be 42, but she is still Carole’s little girl, and to watch her go through this and withstand the bullying pressure to explain must have been desperately upsetting.”
