You're welcome!
Yes, I am planning to teach her katakana eventually, but not until she knows all her hiragana. I'm using this activity book which she likes:
http://www.amazon.com/My-First-Hiragana-Activity-Book/dp/0486413365/ref=pd_sim_b_17 but have not found a similar one for katakana. Also, our progress in Japanese is kind of slow, because we are teaching her 5 other languages as well, and we only get to do Japanese once or twice a week. So I don't expect we'll get to katakana anytime soon.
What Japanese learning materials are you using? Any good ones you can recommend?
