Kanye's been sleeping on the job -Kim Kardashian

Saint West just made his public debut in honor of his grandfather, Robert Kardashian's birthday ... but there's a whole lot of daddy Kanye West in his face.

Kim Kardashian just posted the first shot of the nearly 3-month-old tyke. Kim captioned the pic: "Today is my dad's birthday. I know there's nothing more in the world he would have wanted than to meet his grandchildren. So I wanted to share this pic of Saint with you all." 

Speaking of dads ... Kanye's been sleeping on the job. Kim also posted a pic of 'Ye and North passed out in the middle of a shopping trip for baby stuff at Bel Bambini.

Shop till you drop, right?
