I've been looking for nice blogs written by parents raising bilingual/ multilingual kids because you might be interested to read about their experiences at home. Most likely, their experiences are very similar to yours.

Here are some I have found that you might like.  Plus if you are already following a blog with similar themes, raising kids to learn Chinese, please give us the heads up and we will add it here.  Thanks.
