Dream Kardashian: See the Birth Certificate Of Rob's Child

Dream Kardashian's birth certificate checks out -- she was born on 11/10, Rob's the dad, Blac Chyna's the mom ... and the doctor who delivered the kid has seen multiple Kardashian vaginas!

 TMZ has obtained a copy of Dream's birth certificate, which lists Dr. Paul Crane as the delivery doc. It's an encore performance ... he did the same for Kim, Kourtney and even Kris!
 We're told Kim and Kris referred Chyna to the man the Kardashian women trust with their lady bits ... and Crane was booked for the birth.
