Well the answer is simple because she showed off her mum skills while on vacation in Greece. In the photo below Kim showed off her mother skills with nephew Mason Disick. Kim cradled Mason lovingly while the rest of the family enjoyed their beautiful time on a rented yacht in the middle of the Greek islands. She totally looked like a mommy in charge and didn’t even seem to be missing out on all the fun the rest of the Kardashians were having.
On a more serious note, I believe Kim would be a mum who would readily spoil her baby with all the goodies she can lay her hands on. On the other hand, Kanye looks like some stern, serious dude who would won’t be taking nonsense from his kid. Or maybe not.
