Kourtney Kardashian has done some pretty crazy things on camera, from delivering her own baby to giving sister Khloe a bikini wax.

On Sundays episode of "Kourtney and Kim Take Miami," the eldest Kardashian sister helped out a sibling again ... in yet another TMI moment.

Kim was suffering from psoriasis, a skin condition that causes skin irritation and redness. The psoriasis was flaring up, causing a desperate Kim to find a solution. Watch below (warning, this is PG-13 content):

That's right, Kourtney squirted and rubbed her breast milk on Kim. Apparently it worked though, as Kim's redness seemed to be disappearing.

Kim better get less squeamish around breast milk, as she's pregnant with Kanye West's child.
