She must be my daughter because she's "fine"

Lately Astrid has tickled me by saying that she's "fine".

Me: "Astrid do you need to potty?"
Astrid: "No, I'm fine."

Me: "Astrid, is your diaper wet?"
Astrid: "No, I'm fine."

Me: "Astrid, are you thirsty?"
Astrid: "No, I'm fine."

Me: "Astrid, do you need help?"
Astrid: "No, I'm fine."

Sometimes it's, "No, I'm fine Mommy."

I have to laugh because that's my line. I have a strong independent streak in me and whenever asked I always say I’m "fine." Now I'm seeing my daughter has the same.
