Possessive

Keeley and Kayden both do a lot of talk revolving around possession. There is a lot of "yours" and "mines". Yesterday we were driving in the car and had a funny conversation about it:

Keeley: Daddy is a boy.
Me: Yes. Daddy is a boy.
Keeley: He is our boy.
Me: (laughter) Yep, I suppose Daddy is our boy.
Keeley: We are his girls.

How cute is that?! We sure love our boy!
