18. He Has Only One Interest
On the flip side of being interested in a hundred thousand different things, some kids are deeply intrigued by one thing in particular. The six-year-old who has already checked out all of the library books about dinosaurs and cannot get enough about dinosaurs because they fascinate her to no end. Or, the two-year-old who only wants to talk about firefighters and go to the fire station and play with his toy firetruck. The four-year-old who goes to the zoo only to see the monkeys, and then they only want to look at books about monkeys and watch shows about monkeys. Those kids know what they enjoy, and they are smart.
