Taking to Instagram, the royal, 30, celebrated her first Mother’s Day by posting an adorable snap of her son August, who was born on February 9.
Although his head is turned away from the camera, the young royal can be seen donning a patterned babygrow adorned with whales, a knitted white cardigan, matching hat and fluffy rabbit slippers.
Princess Eugenie also paid tribute to her mother Sarah Ferguson, 61, in a throwback snap where Fergie can be seen holding her as a baby back in 1990.
Alongside the touching tributes, the Queen’s granddaughter penned: ‘I’m so excited to be August’s mum and as you can see I’m enjoying my first Mother’s Day.’
‘I’m also celebrating my beautiful Mumma with this picture of us from March 1990. You’ve taught me so much. Happy Mother’s Day to all.’

Royal fans were quick to comment on the adorable snap, while Eugenie’s brother-in-law Edo Mapelli Mozzi, Princess Beatrice’s husband, ‘liked’ the post.
‘Happy Mother’s Day to you beautiful photos,’ wrote one, while a second penned: ‘Happy mother’s day, dearest.’
A third added: ‘Happy 1st Mother’s Day Princess Eugenie. Many blessings to you and your little one.’
The daughter of Prince Andrew and Sarah Ferguson welcomed her first child, who is 11th in line to the throne, with Jack on February 9 at London’s Portland Hospital. The couple were pictured leaving the hospital three days later on February 12.
Last month, the new mother revealed the name and shared her first family picture with her son – the Queen’s ninth great grandchild – which is thought to have been taken in the grounds of Frogmore Cottage, where the couple are currently living.
Posting a series of photographs on Instagram, the Queen’s granddaughter wrote: ‘Thank you for so many wonderful messages. Our hearts are full of love for this little human, words can’t express. We are excited to be able to share these photos with you.’

Eugenie went on to reveal the name was a touching tribute to Queen Victoria’s Husband Prince Albert, whose birth name was Franz Albert August Karl Emanuel, and Prince Philip, who is currently in hospital, writing: ‘On his grandfather’s birthday weekend, thinking of my grandfather, we are introducing our little boy.
He is named after his great grandfather and both of his 5x great grandfathers.’
Throughout the day, the Royal Family have been celebrating Mother’s Day on social media, with Kensington Palace leading the touching tributes.
Prince William and Kate Middleton shared home-made cards from Prince George, Princess Charlotte and Prince Louis which were addressed to their ‘Granny Diana.’
The cards were shared by the Kensington Palace official Instagram account, with a sweet message encouraging those struggling with bereavement.
Noting this Mother’s Day was ‘different,’ the Palace revealed Prince William, 38, and Kate Middleton’s children write letters to their paternal grandmother each year on Mother’s Day.
