The pregnant US reality TV star - who is due to give birth to her first child with partner Scott Disick in December - is "scared" about motherhood because she doesn't have any idea how to look after a newborn.
She told E! Online: "I don't think I have ever changed a diaper. I am sure that I helped with my younger sisters Kendall and Kylie, but I don't remember. When Kendall was born I was 16. You just get your driving license then and you're never home."
The 30-year-old beauty - who starred in 'Keeping up with The Kardashians' with her siblings - admits she will be relying on her family for support.
When Kourtney and sister Khloe, 25, went for lunch with a friend recently, the younger sibling cared for their pal's baby because Kourtney was too nervous.
Kourtney explained: "Khloe knew everything to do, like holding her perfectly, playing all these games. The girl was laughing. When I tried to hold her, I was like, 'Khloe, take her, take her!' I was so scared."
As her bump grows, Kourtney says she is also having to deal with obscure food cravings and is constantly tired.
She laughed: "Recently I got tuna on a bagel and pickles and sauerkraut and then bagel chips dipped in Thousand Island dressing. But after that, I literally went home because I was so tired. I made Scott come home and take a nap with me.
"We talk about marriage all the time. I just feel like there is so much to do... There is no rush. We should everything for the baby right now and I'll worry about myself later."
