Kenley: "Mom, can you get Adley out of here?"
Me: "No, why do I need to take Adley out of the tub?"
Kenley: "She's a 'zaster."

Bath.

*After slathering herself head to toe in butt cream...*

"Definitely need to take a bath."

Bath.

*Grandma gets up from a nap with hair all over*

Grandma: "Did you have a bath last night? Your hair smells good."
Kenley: "Grandma, your hair needs a bath."
