Abbie: How old is Amie's head?
Mama: Her head is 1 year old... like the rest of her!?!
Abbie: I really think it is still zero.
Mama: No, her head had a birthday just like the rest of her.
Abbie: But her head is only as tall as this. (places hand above Amie's head)
Mama: Abbie, She is tall enough to be one... and so is her head.
Abbie: She is a baby until she turns five.
