We hope to encourage George and Charlotte to speak about their feelings, and to give them the tools and sensitivity to be supportive peers to their friends as they get older.
From taking photographs of George and Charlotte, I have been struck by the wonderful lack of self-consciousness that you see in photographs of children, without the self-awareness that adults generally feel.
Actually William wasn't there for quite a bit of the time initially, he wasn't there for Freshers Week, so it did take a bit of time for us to get to know each other but we did become very close friends from quite early.
I think, the people around home are very supportive to us.
I'm still very much Kate.
It's obviously nerve-wracking, because I don't know the ropes really, William is obviously used to it, but I'm willing to learn quickly and work hard.
I have learned that delivering the best possible palliative care to children is vital, providing children and their families with a place of support, care and enhancement at a time of great need is simply life-changing.
Around-the-clock support is crucial for children receiving palliative care. They and their families often need help every hour of every day, both in hospices and at home.
All of us know someone who has been through difficult emotional times, and we know how hard it can be to see a way forward.
We need to help young people and their parents understand that it's not a sign of weakness to ask for help.
No parent would fail to call the doctor if their child developed a fever.
I was lucky. My parents and teachers provided me with a wonderful and secure childhood where I always knew I was loved, valued, and listened to.
I often get asked why I decided to spend time highlighting the mental health of children.
It is our duty, as parents and as teachers, to give all children the space to build their emotional strength and provide a strong foundation for their future.
We have heard time and time again in the course of our work how talking can help heal the hidden challenges we can't deal with alone.
It's very special having a new little girl.
I feel very, very lucky that George has got a little sister.
I feel enormously proud to be part of East Anglia's Children's Hospices and to see the wonderful life-changing work that you do.
Imagine if everyone was able to help just one child who needs to be listened to, needs to be respected, and needs to be loved - we could make such a huge difference for an entire generation.
Throughout my work with family and child support organizations, one thing that has stood out to me time and again is that getting early support for a child who is struggling to cope is the best possible thing we can do to help our children as they grow up.
