In September, Kourtney had to undergo a life-saving fetal surgery.

She took to her Instagram days after she was released to thank the staff at the hospital, as well as Travis for being by her side.

‘I will forever grateful to my incredible doctors for saving our baby’s life. I am eternally grateful to my husband who rushed to my side from tour to be with me in the hospital and take care of me afterwards, my rock.’

Kourtney has three children with ex-partner Scott Disick: sons Mason, 14, and Reign, nine, and daughter Penelope, 12.

Travis is dad to son Landon, 21, daughter Alabama, 18, and stepdaughter Atiana, 25, with ex-wife Shanna Moakler.

Adding: ‘As someone who has had three really easy pregnancies in the past, I wasn’t prepared for the fear of rushing into urgent fetal surgery. I don’t think anyone who hasn’t been through a similar situation can begin to understand that feeling of fear.

‘I have a whole new understanding and respect for the mamas who have had to fight for their babies while pregnant.’

In December 2022, Kourtney revealed she stopped IVF 10 months prior, because it caused her spiral into a deep depression among other symptoms.

She had been very open about her struggle with IVF on Hulu’s The Kardashians.

Kourtney and Travis conceived Rocky naturally, she revealed in an interview with Vogue in November 2023.

‘We just got pregnant naturally. It was an indescribable feeling. Shock, then super-happy, fear seats in, worry, but I remember then to have gratitude.’
