This will be girl #9 in the Kardashian clan -- not including Kris herself -- and we've learned it bodes well for one of those ladies in particular.
We spoke with a notable child psychologist, who tells us North West and baby #3 will probably form a closer bond than Saint might with his new sis. And the reason's simple: sisters gravitate to their sisters. You don't gotta tell us ... or the Kardashians, either.
Kind of a bummer for Saint, though -- especially since Kim recently said North "does not like" him ... and doesn't seem to be getting past the meanie phase.
