Why this matters
Sound localization requires the brain to calculate millisecond differences between both ears, an essential precursor for speech comprehension.
What you need
- A steel katori with 3-4 dry rajma beans inside, taped shut
How to do it
Place baby on their back looking straight up at you.
Move slightly to their left, about one foot away, and gently shake the katori rattle.
Wait patiently as baby pauses and slowly turns head and eyes toward the source.
Smile and praise: 'You found the sound!' Then repeat softly on the right side.
Finished doing this activity?
Mark it done when you and your child have tried it.
Parent tip · What to say
“Use soft, pleasant shaking rather than sharp, loud rattling to prevent startling them.”
What your child practices
Auditory localization, spatial awareness, and coordinated neck turning.
Safety & Supervision
Ensure containers with small beans are securely taped shut so no loose items escape.
