3 going on 65

Recently Laney has taken to talking like a 65 year old grandma. No one knows why, but here are some examples:

I

Laney: Mama? Do you miss my daddy?

Me: Yes. Do you?

Laney: Yes, because he is so adorable.

Me: [laughing] He is pretty adorable, isn't he?

Laney: Yes, he is and I want to squeeeeeeeze him.

II

Sugar booger. She calls people sugar booger.

As in, "Bye sugar booger daddy."

"Goodnight, sugar booger mommy."

"Oh, you are such a sugar booger."
