"Jesteś dużą dziewczynką."

Translation: You are a big girl.

[Silmendil]

For you.

[PierreMDL]

Obligatory

[Schmoople]

Does this mean literally as in size, or that the girl is grown-up in some way? Or can it mean both?

[immery]

I'd say both. but it's big (little girl), so literally it is about a young girl big for her age. But figuratively you can say t to an adult woman.

[AndrewWawr1]

I say this to my 4 yr old daughter a lot

[Helena834099]

But please never to your 16 year old. She'll stop eating.

[Lee262494]

How rude, I would get a slap if I say that!!!

[Jellei]

From your 10-year-old daughter?
