Marek is too young to be signing yet, only 8 months. Zia's Auslan hasn't really improved in months and months. Her speech hasn't much either, so they're not impeding each other. She's just too busy climbing on the couch to stop and look/listen! She's starting to sit and listen to me reading books again, if I catch her at the right time, so maybe she'll become more receptive again over the next few months. I'm hoping so, but it's sort of hard because Rich won't sign with the kids.
