Duchess Kate talks about 'simple moments' she cherishes as a mother in heartfelt letter

Duchess Kate has been on maternity leave since giving birth to Prince Louis last month, but that hasn't stopped her from supporting the causes she loves.

The 36-year-old royal, who is a patron of East Anglia's Children's Hospices (EACH), wrote a letter to mark Children's Hospice Week. In the heartfelt note, she wrote about her own experiences as a mother to Louis, 4-year-old Prince George and 3-year-old Princess Charlotte.

"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." the duchess wrote. "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 continued: "I hope you will join me in supporting Children's Hospice Week this year. Together we can champion the vital role that children's hospices play in helping seriously ill children and families to have more precious moments."

For Children's Hospice Week in 2016, the Duchess of Cambridge released a video of support. She took on the patronage of EACH back in 2012.

This past weekend, Kate made her first public appearance since giving birth at Prince Harry and Meghan Markle's wedding. The royal stunned in an Alexander McQueen ensemble that she's worn on two previous occasions. For more on Kate, watch the video above.
