Mother knows best?

Kourtney Kardashian -- who welcomed son Mason with beau Scott Disick last December -- has apparently sampled her own breast milk.

"Kourt just admitted that she tasted her own breast milk. Ummmm TMI," her sister Khloe Twittered Thursday.

Kerrie Conway, an international board-certified lactation consultant, tells UsMagazine.com "it`s not dangerous" for women to drink their own breast milk.

"Breast milk has nutrients and anti-bodies that can help boost the immune system," she tells Us. (It remains to be seen whether consuming nutrients found in breast milk will improve the quality of a woman`s breast milk down the line.)

But the practice is somewhat unusual, she says.

"Occasionally, I`ll have a mom say, `Hey, I tasted my breast milk.` It`s not one of those things that`s unheard of," Conway tells Us. "But it`s not like in my professional career, I run across it daily."

Khloe, 25, says she is still getting used to her sister`s breastfeeding ways.

"Wow my sister has changed," she previously Twittered. "She used to whip her boobs out for no reason. Now she does it to feed her child (sic)."
