This double CD set includes an introduction to the program with excerpts from the Leader's Guide. The second CD has fun songs that help children change their engine speeds. As children get familiar with the Alert Program® CD, they will get to know their favourite songs and might request a song that will help them with their engine level. For instance, a child might say something like, "Mom, it's time for me to go to sleep and my engine is running high. Could we play that song off of the Alert Program® CD?"
