PROMPT: The "M" Command
This command is for the "M" (mmmmm) sound.
To do this PROMPT command: Facing the child, place the back of index and middle finger on the child's lips. Say the sound "mmmmm" as you have your fingers on the child's lips and then pull the fingers away. Do this to help encourage the child to say the "m" sound. Say the sound when you are giving the PROMPT command and also as you move your fingers away. Some support may be necessary with your other hand for the child's head/mouth.
