Kate Middleton discusses motherhood in a letter to support Children's Hospice Week and it made us love the royal mom of three even more.

In the heartfelt letter, Middleton talks about how much she cherishes her growing family.

“Spending quality time together is such an important aspect of family life and for me, as a mother, it is the simple family moments like playing outside together that I cherish," she wrote in the piece that was released last week.

The Duchess of Cambridge goes on to reveal the theme of this year's Children's Hospice Week, which is “Life Is Short”. Middleton was very touched by how many children were sharing what they love most in life, and she praised all of those young people who were reminding the world just how precious time is for all of us.

“By supporting Children's Hospice Week, we can help them spread joy and positivity across the UK, encouraging everyone to make the most of moments that matter," she continued on in her letter.

For those who are not exactly sure what Children's Hospice Week is all about, it is described by the Palace as a time for raising awareness and funds for children (and the families of children) who have "life-limiting conditions".

The letter also praises East Anglia's Children Hospices, an organization that the Duchess has been a part of since shortly after she married Prince William. She reveals that the support that they provide for children and their families is truly life changing.

This is really the first glimpse inside motherhood that Kate Middleton has shared with the public. Although she is constantly portrayed smiling, laughing and bending down to speak to Prince George and Princess Charlotte, Middleton has never really discussed her experience as a mother.

Children have always played a special part in Kate Middleton’s role as the Duchess of Cambridge. She is constantly advocating for more awareness when it comes to mental health for kids in the United Kingdom. Middleton loves being a mother to her three little ones and that is driving her to help fight harder for those children, whose families are in need of some assistance.

Great job Kate!
