Of course, with so many couples kickstarting their lives together, babies were sure to follow. Aside from the slew of relationship drama, extravagant celebrations, and ongoing tensions, fans also got to witness the family grow. Kris Jenner became a grandma several times over; all of her grandchildren up to now have been born since the show began airing (via Elle).

Kim Kardashian and her ex-husband, Kanye West, are parents to North, Chicago, Psalm, and Saint. They have the most children out of all the siblings (via PopSugar). Kourtney Kardashian and Scott Disick co-parent three children together and were the first to become parents. Their children are Mason, Penelope, and Reign. Longtime fans likely remember how Kourtney actively played a part in the delivery of her firstborn in Season 4 (via People). 

Kylie Jenner and her boyfriend Travis Scott have two children, Stormi and a son that we do not know the name of yet (via CBS News). Rob and Khloé Kardashian each have one child. Rob and his former fiancé Blac Chyna have a daughter named Dream. Khloé and Tristan Thompson share a daughter named True. As of now, Kendall Jenner remains the only sibling that is childless.

With fans heavily invested in the lives of the family members, it has led to major success for the show.
