King Cairo Teaches Sister, Dream How To Send A Text Message

He may only be four but already this tiny tot is a tech wiz. And, if King Cairo has anything to do with, his baby sister Dream will soon be too.

Last night Blac Chyna shared a Snapchat of her four-year-old son showing his sibling how to send an emoji.

The doting big brother lay down next to his three-month-old half sister and showed off his superior technology skills.

The four-year-old whose father is rapper Tyga tapped away on an iPad, which his mom thought they were watching a movie on and then tried to teach her.
