Prince George, Princess Charlotte and Prince Louis are the ‘centre of William and Kate’s world’ and are showing ‘extraordinary resilience’ in the face of the Princess of Wales‘ cancer battle, an insider has claimed.

Earlier this month, the royal mother-of-three, 42, announced in an emotional video message that she is undergoing ‘preventative’ chemotherapy after cancer was discovered following her major abdominal surgery in January.

In the video, the Princess explained how ‘it has taken us time to explain everything to George, Charlotte and Louis in a way that is appropriate for them’ and to ‘reassure them that I am going to be okay’.

Speaking to PEOPLE magazine, an insider revealed that the Prince and Princess of Wales’ children Prince George, 10, Princess Charlotte, eight, and Prince Louis, five, have been a source of support during Kate’s treatment.

Describing how they ‘buoy [Kate and William] with smiles’, the insider said: ‘The children are at the centre of their world.’

They added: ‘You take heart from the extraordinary resilience of children.’

The insider also claimed Kate and William are also prioritising family time as ‘having fun together when they can is very important’.

It is believed that the Princess of Wales announced her cancer diagnosis on 22 March as this was the day George, Charlotte and Louis broke up from Lambrook School in Bracknell for their Easter break.

The announcement may have been timed so that her children would not immediately face questions in the playground after the news was made public.

The family are reported to have spent the Easter holidays together as they adjust to Kate’s diagnosis, which was discovered in post-operative tests following her major abdominal surgery.

According to the Mirror, an aide said: ‘The family just want to go away for Easter, spend time together, the five of them, close off from the world and move on.’

They usually spend the children’s holidays at spacious Anmer Hall in Norfolk – their country home – and are known for revelling in ‘outdoorsy’ activities such as cycling and walking.

In the emotional message, which was filmed in Windsor, Kate revealed the news had come as a ‘huge shock’ and that she and William ‘have been doing everything we can to process and manage this privately for the sake of our young family’.

Speaking from a bench surrounded by daffodils and spring blossom, she said: ‘It has taken us time to explain everything to George, Charlotte and Louis in a way that is appropriate for them, and to reassure them that I am going to be ok.

‘As I have said to them; I am well and getting stronger every day by focusing on the things that will help me heal; in my mind, body and spirits.

‘Having William by my side is a great source of comfort and reassurance too. As is the love, support and kindness that has been shown by so many of you. It means so much to us both.’

Kate revealed that she had been diagnosed with cancer after undergoing a planned operation at The London Clinic in January.

She explained: ‘In January, I underwent major abdominal surgery in London and at the time, it was thought that my condition was non-cancerous,’ she said.

‘The surgery was successful. However, tests after the operation found cancer had been present.

‘My medical team therefore advised that I should undergo a course of preventative chemotherapy and I am now in the early stages of that treatment.’

The announcement sent shockwaves around the world and came after weeks of speculation – and wild conspiracy theories – about her health.

It also creates a fresh crisis for the British Royal Family at a time where King Charles is also battling cancer. In January Sarah, the Duchess of York, was diagnosed with skin cancer, just six months after being treated for breast cancer.
