What do I need?

• Rattle

How do I do it?

1. 01

   Set up the space

   Lay your baby on their back on a comfortable surface. Bring your face about 30 cm from theirs, so they can see you clearly.

2. 02

   Move the rattle

   Pick up something that makes a sound (a rattle, a bell or a musical toy). Move it slowly from left to right in front of their eyes, about 20–25 cm from their face.

3. 03

   Add the sound

   Keep the sound going as you move it, so they see and hear it at the same time. Watch their eyes: at first they follow it in little jumps, then more and more smoothly.

4. 04

   Stop when they tell you

   When they look away or start to fuss, leave it for today. That's their way of telling you they've had enough.

What are they learning?

As they follow the rattle, they practise moving their eyes from side to side without losing sight of it, and the sound helps them connect what they see with what they hear. Around 3 months, many babies start reaching for the rattle, even if they can't grab it yet.

• Hearing

  Connects the sound of the rattle with what they see

• Visual movement

  Follows an object moving from side to side with their eyes

• Visual focus

  Keeps their eyes on the rattle without losing track of it
