It helps when the family gets involoved and does training to. An expert consultant trains everyone and guides you through the program. If you have any questions about what to do next you ask that person. You have two hour sessions with the child with a ten minute break after the first fifty minutes. Within those two hours you have trials.
Trials are about a two minute process or so.
There are different programs that you work on during these trials. The example I am going to use is Non-Verbal Imitation. With this program you sit facing the child with a table beside you. Then you proceed to do something that you want the child to do. An example of this would be putting a block in a bucket.
