According to an blog post I found today, teaching a baby sign language can help him or her to learn to read at an very early age.
The post is about a 17 month old girl who can read, as she demonstrates on the video embedded in the post. Her parents, who are both Speech Pathologists, have taught her American Sign Language as well as English and have encouraged the development of her language skills, though they haven’t drilled her in reading. Learning sign language can also help children develop their spatial and visual abilities apparently.
Have you heard of any other similar cases?
