My son is normal and he is interested at ASL since he was about 3 years old. By the time I realized that how much fun he had and was going to find a ASL class for him, but one class was cancelled after we signed up. The teacher just got so busy. Then the other one only took the kids who were under 3. Not so many ASL classes for the little ones in our area. However, I checked many different ASL DVDs and books from the local library but they were not very interesting and fun as Signing Time. However, I purchased the whole set of the flash cards last Christmas. It reminds me what I have learned way back to college. It is also very good for me to learn together with my little boy. Sometimes he is daddy's little ASL teacher. He teaches his daddy what he learns since my husband has never learn ASL before. Many people I know or meet in public all know about Signing Time and they love it so much as we do. For us, Singing Time has very great and practical and useful products. Highly recommended. However, we have been enjoying a lot. (Posted on 12/1/08)
