To turn expander:
- Find a place in the house that is comfortable, where your son/daughter can lie on their back with their head tilted backward. (Looking up toward the ceiling).
- Sitting along side of them, have them open their mouths.
- Insert the key into the hole in the expander.
- Then turn the key toward the back of their throat.
- To complete the turn remove the key STRAIGHT down. Make sure that this is straight down because you do not want to reverse the turn.
HINT: Be sure to turn the key all the way toward the back of the throat. That way, you will be able to properly fit the key in the next hole.
