Kylie Jenner, the 27-year-old mom of two, has shared her personal experience with postpartum depression and the challenges she faced while naming her son Aire.

In a recent interview with British Vogue, Kylie talked about her struggles with depression, which lasted almost a year after both of her children’s births. Kylie revealed that she had a hard time finalizing a name for Aire, and for a long time, she called him “Knight.” Her daughter Stormi, 6, still remembers this and asks if she recalls when Aire’s name was Knight. Stormi even prefers the name Knight over Aire. Kylie advised her friends to pick a name before the baby arrives, as the hormonal changes can make decision-making difficult.
