Zoë: I wish Baby Doll would hurry up and grow up.
Me: But Baby Doll is a doll, honey.
Zoë: I want her to be a big girl, like me.
Baby Doll is, of course, Zoë's baby doll. I would say favorite if there were another, but she has never wanted another baby doll. I once bought her one and she completely rejected it -- going as far as throwing it out of her room into the hallway. It was a beautiful doll, too. Finally, I gave it to my niece rather than see it constantly rejected. Zoë has the whole kingdom in stuffed animals, but there is only one Baby Doll.
So, how do I explain that she will never grow up?
