When using the ultrasound machine for pediatric speech, it is important to first explain what each piece of the ultrasound machine is, and how it will be used. This is important because while older individuals will understand what these tools are, they may be new and frightening for a child who has never used the machine before.
For younger children, generally under the age of 9, you may have to hold the probe for them, or if they are comfortable, the headset may be a viable alternative to holding the probe. You also will need to provide more verbal cues for head position so they continue to hold their head still, so the ultrasound probe does not become loose, and the image remains intact. You will also need to multitask to ensure that the probe remains in the correct location so the image remains clear and you can manage what you are working with on the screen.
Since their anatomy is generally smaller, use the smaller probe to conduct the study and proceed with the steps, as seen in the Ultrasound and Video tab.
Ultimately, the study should be conducted in a relatively similar manner, however, it may be helpful to remove other distractions within the room and communicate more clearly and thoroughly about what you are doing as you are doing it.
