Step 2.3 Deliver prompts following the toddler's attempts
If the toddler's response is incorrect, provide positive feedback and the reinforcer to the toddler. This can be accomplished by interrupting the incorrect response, and then deliveriving the next prompt in the hierarchy. Also, deliver the controlling prompt last if toddler does not respond to the other levels of the hierarchy.
Use the response interval prior to delivering another prompt in the hierarchy.
