Hi, I have a 14-month old daughter with Down syndrome. We've been reading books to her practically since birth but I have not yet started a formal reading curriculum. I am researching various programs and I'm happy to have found this forum!
We started the Baby Signing Time videos at around 9 months. I wish I could brag and say she knows zillions of signs but the reality is that the only two she uses consistently are waving and clapping. She apparently hasn't yet caught on to the idea that symbols (signs, written or spoken words) can represent objects. However, she is very interested in picture books so I believe she understand more than she lets on at this point!
