Children learn by imitating the speech and language of others. Children learn from watching and listening to their brothers, sisters and parents.
Most children attempt to imitate the actions that they see others do.
They try to copy everything we do. Children imitate the sounds we make and the words we say. Once children begin making sounds and words, parents can bombard them with thousands of new words. Children with delayed speech and language may not be picking up on the models or be able to copy them because it is a little too difficult for them to try. If a child is using single words, you want to encourage him or her to use two words at a time.
