There are many different sign systems. American Sign Language is a natural one and the most widely used signing throughout North America. It is overwhelmingly preferred by Deaf persons because it is full, natural language. Children exposed to a full, natural language and a print language from the earliest possible age tend to do better in reading and writing. Parents need to consider how much they influence the future behaviour of their children by setting an example.
Children tend to copy their parents' behaviour.
If parents smoke, their children will likely become smokers also. Likewise, if parents are readers, their children will be apt to read. There is strong evidence supporting the notion that children raised in families that enjoy reading and writing as an activity are inclined to become good readers and writers. It is important that parents are seen to be reading and writing. Even if parents are unable to increase their reading times, they can help their child by ensuring that books and reading material are easily available at home.
