15. Baby Kendall
Kim was 16 and Kourtney was 17 when baby Kendall came along. But even though there was a huge age gap between them, the sisters loved having a little one around the house again.

"My baby Kenny! I was 16 years old here and you weren’t even a year old," Kim posted on Instagram on Kendall's birthday. "I can’t believe you’re 25 years old now. I always couldn’t wait to see what you would grow up to be like! LOL you were always my baby Kenny doll! I’m so happy all of our siblings found each other in this lifetime!"
