To mark the special occasion the 33-year-old reality TV star posted a picture of herself and her daughter North West sharing a heart-warming moment.
The black and white photo shows Kim blowing a kiss to 11-month-old North in what appears to be her nursery. The room is furnished with a plush fluffy rug and toys can be seen in the background, including a lion and giant giraffe.
Kim also has a star-shaped room thermometer and white noise machine, which is often used to soothe babies to sleep.
"This little girl has changed my world in more ways than I ever could have imagined!" wrote Kim alongside the touching image. "Being a mom is the most rewarding feeling in the world! Happy Mothers Day to all of the moms out there!"
Kim's fiancé Kanye West made sure that she received a Mother's Day present on behalf of their baby daughter.
"I woke up to a wall of roses, hydrangeas and peonies!!!" posted Kim as she showed off the large floral display. "I have the best fiancé in the world! I love you so much baby!!!! #HappyMothersDay".

For Kim, Mothering Sunday came the day after she celebrated her bridal shower surrounded by family and friends. And the picture she shared of herself with North appeared to have been taken on Saturday, as she was snapped in the special white dress she wore for her bridal party.
The celebration was held at The Peninsula Hotel in Beverly Hills, exactly two weeks before Kim and her rapper fiancé will tie the knot in Paris on 24 May.
In a nod to their choice of wedding destination, Kim's bridal shower was Parisian-themed and the guests were given a box of Ladurée treats and a small white chocolate Eiffel Tower statue.
Kim's nearest and dearest were all in attendance, including her mother Kris Jenner, sisters Kourtney and Khloé, and half sisters Kendall and Kylie.
