Mother's Day is still months away in the U.S., but in the U.K., mothers will be celebrated this weekend. Princess Eugenie celebrated her first Mother's Day as a parent by sharing a new photo of her baby boy on Instagram.

"I am so excited to be a mom to August. As you can see, I am enjoying my first Mother's Day," she wrote in the caption, accompanied by a photo of August enjoying flowers. The newborn baby was wearing a knit cap, sweater, onesie with a whale on it, and cute bunny slippers.

Eugenie also paid tribute to her own mother, Sarah Ferguson (opens in new tab)." I celebrate my beautiful mama with this picture of us taken in March 1990. You have taught me so much. Happy Mother's Day, everyone.
