How it works

  1. 1~25s

    Start by gently taking your child's legs — hold them just above the ankles. Now give them a little shake, like they're vibrating. Make it playful and gentle — not too fast. Watch your child's face closely. Does they smile or giggle? Does they seem to enjoy this movement from you, you? Tell me what you see in their expression.

    Watch for: Baby interacts positively with familiar caregiver through smiling, vocalizing, or joyful expressions during playful touch.

  2. 2~35s

    Now let's try a different pattern. Start the shaking movement from your child's glutes — that's the bottom area — and let it travel all the way down to their feet. Do this for about 10 seconds, then stop. Wait a moment and watch your child's reaction. Does they look at you expectantly, as if asking for more? Does they show a clear preference for you to continue versus if a stranger were doing this?

    Watch for: Baby shows clear preference for familiar caregiver's touch and interaction through seeking behavior or positive responses.

  3. 3~40s

    Let's do a few more rounds — shake for 10 seconds, stop, repeat. This time, pay attention to your child's emotional awareness. If you were to pretend to look worried or concerned during the shaking, would your child notice and react? Or if you make a really exaggerated happy face, does they mirror your expression? We're looking for signs your child is tuning into your emotional cues during this intimate play.

    Watch for: Baby shows differentiated emotional responses to familiar versus unfamiliar adults, indicating developing social awareness.
