Princess Kate's brother James Middleton shared a heartfelt message to mark a family member's big day.

"Happy 4th Birthday, Isla," James wrote.

"Many of you have been asking if we kept a puppy from Mabel's recent litter and…of course we did…Introducing Isla. Her name is a little nod to her Scottish roots," he shared at the time.

This family celebration came after James accompanied his sister Catherine in completing the Three Peaks Challenge for the Royal Marsden Cancer Charity. 

Upon returning from the mountains, he penned a heartwarming note for the Princess of Wales, who marked history with her meaningful move for cancer charity.

He penned, "Seeing how far you’ve come is nothing short of inspiring. Your strength, resilience, and determination, all while being the most amazing mother, wife, daughter, and sister, inspire me and so many others every single day."
