"Do we speak Kjelsås?"

Aidan has been learning a lot about different countries and languages, especially since our recent trip to Turkey. And some of his classmates in barnehage are from foreign lands, so he´s been extra curious about languages lately.
On a recent bus trip to the Teknisk Museum (Oslo´s science museum), he asked where the museum is and I said in Kjelsås, which is a nearby area of Oslo. He then asked me, "do we speak Kjelsås," assuming that they speak a different language there. He´s good at both English and Norwegian, and can switch between the two without a problem. He occasionally asks how to say something in Norwegian, as he is a bit more fluent in English since that´s what we speak at home.
