Here is a video from tonight, including the first time Xav has said"OK". What an accent!
Here is a video from December 12, in Aachen.
His language skills are developing quite fast now. Xav is trying to copy many words, and his vocabularly is growing; of course, he recognises more words than he speaks. So far he has not put two words together. His vocab is a mix of Indonesian and English. He says "habis" (more or less) when his juice is finished, and he calls juice "juice" (more or less).
It is only in the past two weeks that he has starting speaking more than the most basic words, but he is acquiring new words much faster than I expected.
