The Keeping Up With the Kardashians alum recently took to her social media to reveal the family news. Via her Instagram Story, she shared a number of posts about his condition.
Up first, Kardashian uploaded a photo of the 5-year-old sitting in a wheelchair while icing his arm. Later, she shared a pic of her son cradling his arm after his cast had been set.
“Who do you think cried more today? My baby broke his arm in a few places today. I’m not ok,” Kim wrote, later adding, “Poor baby.”
It isn’t immediately clear how Saint broke his arm.
Saint is the second-oldest of four children whom Kardashian shares with Kanye West. They also are parents to daughters North, 8, and Chicago, 3, and son Psalm, 2.
