Not really worried, just curious.
DS3 is 16 months old, and unlike his twin brother, he isn't very talkative but when he does talk, it's German and he refuses to speak English. He either shakes his head or he replies, "nein."
He has a vast vocabulary of both English (me) and German (DH). He is of British nationality and have only just recently moved to Germany. So, I don't know if it's just from the culture shock, a comfort thing, or if he's picking up that mostly everyone is speaking German constantly.
I've been away for 4 weeks, so other than other DC (who are 5 and under) and DH no one has been speaking English that much. DH and I are fluent in both as are DS1 & DD1 but DH would prefer to constantly speak German all the time. He's very proud of his heritage.
I have a sneaky feeling that DH has completely stopped talking to DC in English since moving. Could this be the cause? Is he copying? He understands me, he just answers in German. DH says he's been doing it for a couple of weeks now.
I talk in my first language as much as possible just so they have variety in a different country.
Has your DC ever done this? Did it resolve itself?
Sorry for the rant!
