No parent would fail to call the doctor if their child developed a fever.
If any of us caught a fever during pregnancy, we would seek advice and support from a doctor. Getting help with our mental health is no different - our children need us to look after ourselves and get the support we need.
Having a child, particularly your first child, is such a life-changing moment. Nothing can really prepare you for that.
I can remember being at Sandringham, for the first time, at Christmas. And I was worried what to give the Queen as her Christmas present. I was thinking, 'Gosh, what should I give her?'. I thought, 'I'll make her something.' Which could have gone horribly wrong. But I decided to make my granny's recipe of chutney.
By far the best dressing up outfit I ever had was a wonderful pair of clown dungarees, which my Granny made.
Together with open conversations and greater understanding, we can ensure that attitudes for mental health change and children receive the support they deserve.

I often get asked why I decided to spend time highlighting the mental health of children.

Every child deserves to grow up knowing their potential and feeling confident that they won't fall at the first hurdle - that they cope with life's setbacks.
I'm still very much Kate.
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.
A child's mental health is just as important as their physical health and deserves the same quality of support.
Change the way we all talk to each other about our mental health.
Sadly, for some mothers, this experience can be made so much harder due to challenges with our very mental health.
Parents, teachers, and other school staff need the tools to help these young people early in their lives. And the earlier, the better. It is proven that early action prevents problems later in life.
Every time Wimbledon is on, I am thinking, 'Yes, I could do the same and get out the racket.' Sadly, not the same results.
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.
There is no rule book, no right or wrong; you just have to make it up and do the very best you can to care for your family.
