Start by forming a circle with pointer finger and thumb and place tips of circle on chin. Then move hand forwards and down to in front of waist, palm down, fingers apart and pointing forward; bounce hand sideways three or more times. (sometimes just slide sideways instead of bounce)
Hint
Little people this tall.
Context for Auslan
More bounces often indicate more children; and location of sign can change to refer to specific children (the children over there, in the distance, would be signed gestured out in the direction of the children)
