The "Big-Gun" for parents to facilitate language development is READING to the child.
Hence, the child might say, "Daddy come." Mother might then say, "Daddy's coming," a rephrase, or "You see Daddy coming," a slight extension.
This intense adult-child interaction will make the language processes seem to grow significantly by the day.
As always, the other BIG GUN for developing language is READING to the child. Again, the vocabulary and syntax contained I books is richer than included in oral dialogues. The child may wish to read the same books many times and this is good for the reasons we discussed under eidetic imagery.
The child will have more time to extract the linguistic principles; and will develop expectancies which will improve his/her listening skills. This will improve their enjoyment which will increase their motivation to use language.
