Kim Kardashian shared on the On Purpose with Jay Shetty podcast how she celebrates her kids' birthdays each year by writing a four or five-page letter to each child detailing their year. Kardashian believes her children will appreciate the letters, just as she did when receiving them from her mother. Kardashian shares four children with ex-husband Kanye West: daughters Chicago, 5, and North, 9, and sons Saint, 7, and Psalm, 4. On Mother's Day this year, Kardashian received a funny card from daughter Chicago, prompting Kardashian to share an image of herself cooking traditional Armenian pancakes on her Instagram Story.
