Kim Kardashian & Kanye West: First Photos of Saint West ... Time for a Checkup

Saint West made his public debut, of sorts, heading out with mom, dad and his big sis to the doctor's office in L.A. on Thursday.

Kanye West and Kim Kardashian took Saint for a checkup, 12 days after he was born. North was not left out. Mom carried her, while Kanye -- covered in a hoodie -- lugged his son ... also covered, in his car seat.

The whole fam was looking healthy and happy, and check out the heels on Kim. Damn!
