Kylie's followers were quick to share their Mother's Day wishes and comments on her post.
"Best mommy! And most beautiful daughter," one wrote.
"HER SMILE IS EVERYTHING," exclaimed another.
"Prettiest baby of all time 😍" another penned. She is stunning, that's for sure!
Kylie also shared a post devoted to her own mum, Kris Jenner.
The black-and-white snap showed a young Kris on board a boat dressed in a white ensemble with block heels.
"A legend," Kylie captioned the throwback picture.
Though it's unknown if Kylie's ex and Stormi's dad Travis Scott participated in the celebrations, he did give a shout out to "all the mums out there" on his Instagram Stories.
Last year, Travis spoiled Kylie on Mother's Day with bouquets of flowers and balloon arrangements.
On top of that, the 28-year-old rapper also gave the makeup mogul a pink crocodile Hermès Birkin bag, valued at around $50,000.
Now, that's not a bad Mother's Day loot.
