Kim took to Instagram on Sunday to share a pic of Kanye resting in bed with their adorable 4-year-old daughter, North, laying on his chest.
"Happy Father's Day!" the 36-year-old reality star and mother of two captioned the pic. "Thank you for being such a good dad to our babies!"
She followed that photo up with another pic showing Kanye and their 1-year-old son, Saint, flying together on a private plane.
The couple, who began dating in 2012, welcomed daughter North in June 2013. The pair got engaged the following October and tied the knot with a luxurious ceremony in Florence, Italy in May 2014. They welcomed son Saint in December 2015.
Kim also paid tribute to her late father, Robert Kardashian Sr., with a cute throwback pic from her childhood.
"God I am so lucky you were my dad. I remember right before you passed away I thanked you for everything u taught me," Kim captioned the pic of her and her father, who died in September 2003 after a battle with esophageal cancer.
"I told u I would raise my kids with everything I learned from you, whenever that time would come," she continued. "Well I kept my promise dad! Thank you for being the best!"
