Some language stimulation techniques, which can encourage and facilitate increased verbal communication are as follows:

Self Talk	Describe out loud to the child what you are seeing, hearing or doing, as the activity is happening. For example "I see the bus coming", "I put the plate away".
Parallel Talk	Describe out loud to the child what he/she is seeing, hearing and doing as he/she does it. For example: "You are throwing the ball", or "in goes the car".
Description	Use labeling or explaining phrases or statements. For example: "That's a big ball", "The water is cold" or "There's a fire truck".
Repetition	Repeat exactly what the child says modeling the correct articulation. For example: if the child says "widdle wed wabbit", you say "little red rabbit".
Expansion	Repeat the child's simple phrase in a more complex way. This indicates your understanding of the child's statement and at the same time gives the child a good model. This also adds complicity to the child's speech. For example: if the child says, "doggy run", you say "Yes the doggy is running".
Expansion Plus	Expand the child's response to an adult sentence as above, then add an additional related comment. For example: the child says "Car go" and you would say "The car is going. It is a red car".
