Are you my mother?

I am beginning to wonder if Addie knows who her mother is.

Addie: Bye bye! I go home find my moder!
Mommy: You're leaving to find your mother?
Addie: Yes. I don know where my moder is.
Mommy: Maybe she's in the front room?
Addie: Bye. I go find my moder.
Mommy: Ok, come back soon!
Addie: K.

Mommy: Did you find your mother?
Addie: No. I don know where my moder is. I go find her.
Mommy: Is she in the bathroom?
Addie: (looking) No.
Mommy: Is she in the living room?
Addie: (looking) No.
Mommy: Maybe your mother is lost.
Addie: Yeah. I can' find my moder. She she she lost!
