I have a 17mth old daughter & started to sign not so long ago....I started reading "sign,sing & play" by monta byrant & used a few flip books (which my daughter loved) she is really enjoying signing..only problem is due to my ignorance I just assumed signing was pretty much the same. She uses some signs (in american sign language) eg:surprised, bored,light on/off & thinks its great1.. I don`t want to confuse her, do you think I should just leave her with her favourite signs or should I convert her to auslan. If so what is the best way to avoid confusion? I plan to teach auslan from now on. Can you tell me more about your book/flip cards?
