Kylie Jenner I'm On Baby Duty! (Hurry Back, Blac Chyna)

11/11/2016 7:32 AM PST

Rest easy, Blac Chyna ... Kylie Jenner's watching your firstborn, and we'll say this for her babysitting skills -- at least every single moment is captured on video.

Kylie was hanging with 4-year-old King Cairo -- Chyna's son with Tyga -- while BC was birthing his kid sister, Dream. Unclear if the kid got a decent meal, brushed his teeth or went to bed at a decent hour ... but he definitely knows how to use the coolest Snapchat filters! That counts for something, right?

Especially love the part where she makes King pick his fave Kardashian-Jenner.
