Kylie Jenner has never shied away from honesty when it comes to her personal life, and her latest conversation about motherhood is no different. The Kylie Cosmetics founder, 28, sat down with Jake Shane on the Wednesday, May 13 episode of his podcast Therapuss and delivered one of her most candid accounts yet a detailed look at just how physically demanding her second pregnancy turned out to be.

Jenner, who shares 8-year-old Stormi and 4 year old Aire with ex Travis Scott, described the experience of carrying Aire as a stark departure from the relative ease of her first pregnancy. She had gone into it feeling confident. By her own account, she was in the best physical shape of her life and had every intention of staying active throughout. What followed was something she had not anticipated at all.

At just 12 weeks pregnant, she woke up one morning and found she could not walk.

Back pain, sciatica and weeks in bed

The culprit was a combination of severe lower back pain and sciatica a sharp, radiating nerve pain that runs from the lower back down through the legs and is not uncommon during pregnancy, though it can range widely in intensity. For Jenner, it was debilitating.

She had already been managing back pain for about three and a half years before becoming pregnant with Aire, and the pregnancy pushed that pain to a level she had not experienced before. There were days she could not get out of bed, not because she chose to rest, but because her body left her no real option.

The situation became more serious as the pregnancy progressed. Jenner revealed that she was 3 centimeters dilated for approximately a month and a half to two months, a condition that prompted her doctor to put her on formal bed rest. Three centimeters of dilation that early or mid pregnancy signals that the cervix is opening ahead of schedule a development that requires close monitoring and reduced physical activity to help carry the pregnancy safely to term.

She described it plainly and without drama, the way someone does when they have already processed a difficult experience and are simply reporting the facts of it.

Weight gain and cravings she did not fight

Beyond the physical complications, Jenner also spoke openly about the changes to her body and her appetite during the pregnancy. Her nausea was severe, and food was the only thing that helped. She leaned into it fully ice cream every night, bagels, carbs in whatever form made the day more manageable.

By the time Aire was born, she had gained 65 pounds, bringing her weight to 210 pounds at delivery. With Stormi, she had gained 60 pounds and weighed 200 pounds at birth. She offered both numbers without apology, framing them simply as part of what her body needed during each pregnancy.

She described carrying Stormi as a much easier experience overall a breeze by comparison. The contrast between the two pregnancies seemed to genuinely surprise her, even in retrospect.

Hiding her first pregnancy and the weight of that secret

The Therapuss conversation also circled back to Jenner’s first pregnancy, which she famously kept hidden from the public for its entirety. She was 19 when she found out she was expecting Stormi, and the news sent her into a period of real fear not just about the pregnancy itself, but about how the people around her would react.

She recalled being terrified to tell her family, though once she did, the response was not what she had feared. No one was upset. But she had already made her own decision before that conversation happened, and she was prepared to move forward regardless of what anyone else said or felt about it.

The choice to keep the pregnancy private came from a place of self protection. She barely left her home during those months, and when she finally announced the news publicly, the emotional release was overwhelming. She described crying for three hours after the announcement not from sadness, but from the sheer relief of no longer carrying a secret that had been pressing on her for months.

Looking back, she acknowledged that hiding it may not have been the right call for her, hinting that a future pregnancy might be handled differently. It was a small but telling admission from someone who has spent years carefully controlling what the public sees and is now, clearly, more willing to let people in.
