How to play
Give him one and shake yours. Stop, and see if he stops. Hide one behind your back and shake it — watch him turn to find the sound.
What you need
Two or three rattles that sound different.
What it secretly builds
Cause & effectTurning towards a sound he can't see is how he learns to locate things with his ears alone. That's the same skill behind hearing his name in a noisy room.
Safety first
One solid piece, no loose beads, and check for cracks before every play.
