Kanye West Shares Sweet Photo Of Saint West Giving Baby Sister Chicago A Loving Kiss

“He loves her so much,” the mom of three wrote.

Despite his best intentions, however, Saint sometimes takes his brotherly duties a bit over the top, according to Kim.

“I always have to watch out for him,” Kim revealed. “He smothers her, and he has this really big hair, so he just jumps in her crib.”
