It's rare that we get to see photos of Kim Kardashian and Kanye West's baby boy, Saint West — but now we have a plethora thanks to Kim's grandmother Mary Jo — aka "MJ's" birthday celebration!

The seven-month-old joined his sister, North West, 3, in addition to his famous extended family for a day at MJ's La Jolla, Calif.-based children's boutique, Shannon & Co.
