29 hour mediation session is 45 minutes was conducted in one session. Frequency perform research on the
behavior of learning to communicate functional requirements infant developmental delay was almost appear to

1 step 2 target infants all three performed with the rapid rise in rates showed the increase. In addition, almost
did not require any action from the baseline step look at the means of communication functions performed by
the use of learning rate was the highest use gestures, gestures and imitating speech coexistence, and gestures
