In a 2020 interview with Poosh, the Lemme co-founder sat down with her sister Khloé Kardashian to discuss motherhood and their differing experiences with breastfeeding.

After Khloé, 39, commented that breastfeeding seemed “so easy” for her older sister and “it wasn’t for me,” Kourtney replied, “It’s not so easy, I remember the first month being the hardest. There is pain involved. The latching, once I figured that out, then it was pretty easy, easier for me, but there was pain.”

“I was definitely comfortable to breastfeed in front of anyone,” her sister replied.
