"I'm so excited to be August's mum and as you can see I'm enjoying my first Mother’s Day," she captioned a photo of her tot sprawled out in a field of daffodils, in addition to a throwback photo of her mom, Sarah Ferguson, holding Eugenie as a baby.
She added, "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 💐."
Of course, people couldn't get enough of the adorable snap. One person wrote, "Happy Mother's Day Princess Eugenie. August is a lucky boy to have you as his mum!😍❤️ you'll be and you'll always be an amazing mum, sure with that!🥰," while another echoed, "Happy Mother's Day to you beautiful photos."
A third user added, "Happy 1st Mother’s Day Princess Eugenie. Many blessings to you and your little one ❤️."
After Eugenie gave birth on February 9, the Palace announced the news about her latest arrival.
"Her Royal Highness Princess Eugenie was safely delivered of a son today, February 9 2021, at 8.55am at The Portland Hospital. Jack Brooksbank was present,” they said in a statement. “The baby weighs 8lbs 1oz.”
The statement continued, "The Queen, The Duke of Edinburgh, The Duke of York, Sarah, Duchess of York, and Mr. and Mrs. George Brooksbank have been informed and are delighted with the news. This is Princess Eugenie and Jack Brooksbank's first child, The Duke of York and Sarah, Duchess of York's first grandchild, and the ninth great-grandchild for The Queen and The Duke of Edinburgh. Her Royal Highness and her child are both doing well."
The mom-of-one then shared her son's moniker on February 20, writing, "We wanted to introduce you to August Philip Hawke Brooksbank. 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."
