Isla McNabb’s ability to read back words written on an erasable tablet led her parents to contact Guinness World Records

Reading words aloud that adults scribble on an erasable tablet may not be the way many children spend their second birthdays. But it’s how Isla McNabb celebrated turning two, and it put the native of Crestwood, Kentucky, on the path to become the youngest ever female member of Mensa, the world’s oldest high IQ society, her parents said in a recent interview.

In a conversation published on Monday, Isla’s parents, Jason and Amanda McNabb, told the Guinness World Records website that they realized their daughter’s intelligence should be assessed after an aunt gave her an erasable writing tablet as a second birthday present.
