Whose precious one?

One day, my sister-in-law was sitting down with Little J in the living room, and following conversation follows:

SIL: You love who more? Mummy or daddy?
Little J: Mummy more
SIL: You love mummy or aunt more?
Little J: Hmm, aunt more.
SIL: You love aunt or grandma more?
Little J: Grandma more.
SIL: Oh, so you are grandma's precious granddaughter.
Little J: And aunt's precious one too.
SIL: How about Baby Jay? Baby Jay is whose precious one?
Little J: Uncle's precious.
(Uncle here is my brother in law)
SIL: So Baby Jay can sleep with uncle in uncle's room, right?
Little J: Yes. And I sleep with you.
