How the six children fit into the family
Brielle and Ariana are Kim’s daughters from previous relationships. Bravo reports that Kroy adopted them legally in 2013. KJ, Kash, Kaia and Kane are Kim and Kroy’s children together. That family structure distinguishes the older daughters from the younger four without changing their place as Kim’s six children.
The family’s television history
Kim and her family became familiar to reality-TV viewers through The Real Housewives of Atlanta and the family series Don’t Be Tardy. Ariana later appeared on Bravo’s Next Gen NYC, according to the network’s profile. The children’s television appearances are part of the family’s public history, but they do not mean every child’s current life is equally public.
