Kourtney Kardashian has discussed her co-sleeping arrangements with her children, revealing that one of her sons slept in her bed until he was 7 and her daughter still does at the age of 10 or 11. There is some discrepancy in the reports about which children are involved and their current sleeping arrangements. Kardashian's mother, Kris Jenner, has expressed disagreement with Kourtney's co-sleeping with one of her younger children, baby Rocky.
