What you'll need

Purpose-made posting toy labelled suitable for children under 3 · Two large rigid one-piece posting shapes

Before you start

Can manipulate large household objects

Best fit: indoors · medium energy · low caregiver effort · low mess

How to play

  1. Show one rigid shape going partly through.
  2. Let your child push it through or retrieve it from the open side.
  3. Explore what happens from both sides.
Make it easier

Use the widest opening with one shape already aligned.

Standard

Work out how large rigid shapes pass through a purpose-made posting toy.

Extend it

Offer the two shapes one at a time and wonder which opening fits.

What you might notice

Changing hand positions and predicting where the scarf appears.

Keep it safe

Use no scarf, ribbon, cord, loop, cardboard or loose fabric. Inspect the under-3 posting toy and rigid shapes, stay within arm's reach, stop mouthing or finger trapping, and count and store all pieces.

Why it may be useful

This gives your child room to explore while you add just enough help to keep the puzzle interesting.

moderate

Guided-play evidence is stronger in preschool samples; toddler activities should remain simple and child-led.
