They grow up so fast! On Wednesday, Kim Kardashian proved once again that North West is her mini-me with a sweet Instagram post. Posing alongside the adorable 6-year-old before she heads to school, the mom of four seized the moment to take the perfect mother-daughter selfie—complete with natural lighting and a scenic view. "School drop off," she captioned the precious snapshot, where North can be seen donning her school uniform and flashing the camera a smile.
