I would prefer not to

So Suzi has just started to say no. She doesn't cry or scream, just respectfully refuses.

We are in bed trying to get her to go to sleep, but she isn't tired. Her daddy decides to give me a break and take her downstairs for a while. He holds his arms out and asks her to come to him.

"Nie," she says indifferently and shakes her head.

Several repeat attempts to get her to come are met with similar replies.

"Nah."
"Nie." And she shakes her head.

"Suzi," I say, "go with your Daddy! He'll take you downstairs so you can play a little while, and maybe have some milk! Honey, what is your deal?"

Daddy holds his arms out for her once more.

"Nie."

I think when she gets a little older, instead of plain old no, I'm going to teach her to say I would prefer not to. Wouldn't that be cute?
