In the comments underneath Kim’s post, Khloe Kardashian also took a moment to give Saint some love, writing, “The absolute cutest!!!!!!!! We all love you Sainty!!!!!”
In addition to her birthday tribute, Kim chronicled each of the rainbows that appeared in her home on her Instagram Story, saying that they were “for Sainty” on his birthday.
When she discovered six in total, one for each year since Saint’s birth in 2015, she couldn’t believe it. ”OMG a 6th rainbow for my Saints 6th birthday!” she wrote. “I’ve never ever had this many rainbows in the same room at once.”
Kim took the collection of rainbows as a special birthday message to her son from her dad, Robert Kardashian, who passed away in 2003. ”Thanks dad! I’ll tell Saint you said happy birthday,” she wrote, adding the hashtag #NeededThis.
