Type that omits all inherited properties?

Say we have

class Person {
  age: number
}
class Child extends Person {
  play() {
    //...
  }
}

class Person {
  age: number
}
class Child extends Person {
  play() {
    //...
  }
}

I want a type that incudes only the fields from Child without the inherited properties.
For example,

type OnlyChild = { play: () => void }

type OnlyChild = { play: () => void }

. Is that possible. I know I can use Omit<> but I don't know what the properties of Person are.
