Aww! What a good big brother...
The reality star posted the photo of the doting big brother giving an affectionate kiss on his two-month-old baby sister's nose.
Along with the pic, Kim wrote, "He loves her so much."
In the image, the baby girl is wearing a grey outfit and is laying on a pink blanket.
Saint, 2, appears to be wearing a camouflage shirt—just like his daddy, Kanye West!
