The first candid snapshot shows Kate sitting in a tree alongside her three children – Prince George, Princess Charlotte and Prince Louis.
In the second, the Princess is beaming as she cradles her youngest son Louis and holds his hand.
The gorgeous images were captured by royal family photographer Matt Porteous and are from a former photoshoot that took place at Anmer Hall in Norfolk last summer.
They were shared on William and Kate’s official Instagram page alongside the caption: “Happy Mother’s Day from our family to yours.”
Followers adored the heartwarming post – but some fans were left confused. The 19th of March this year also marked Father’s Day in a number of European countries, with Kate’s post throwing them all off guard.
“Why is this saying Happy Mother’s Day?” one queried, while a second joked: “Every man in America just panicked for a moment.”
A third noted: “Funny how this year Mother’s Day in the UK and then Father’s Day pretty much everywhere else is on the same day (Father’s Day always St Joseph, 19th of March). Best wishes to every parent then!”
Princess Kate is a doting mother and has previously been praised for her model parenting and down-to-earth approach.
