Hi, I have a five year old Autistic little girl. She was sent to me from God. She doesn't always speak clearly and so we use a lot of sign language. Sometimes she will answer a question with just sign and no voice so it's important for me to look at her when we talk. We started to watch "Signing Time" when my daughter was 2 years old. All I have to do is put the dvd on and she'll come running into the room, she loves it. I highly recommend "Signing Time" to all who want to learn the language an easy and fun way. I sometimes will find myself signing to someone behind a counter at the store! lol
