What the AI looks for in Sorting & Stacking Toys

Piece size
No piece should fit the small-parts test cylinder for children under 3. Stacking and sorting pieces end up in mouths.
Difficulty curve
Shape sorters should start with a few basic shapes, such as circle, square and triangle, before adding complex ones. Too many shapes at once leads to frustration and abandonment.
Washability
Prefer hollow-free plastic or sealed wood. Hollow toys trap water and grow mold.

Brands that matter

  • Fisher-Price: Classic stacking rings.
  • The First Years: Nesting and stacking cups.
  • Melissa & Doug: Wooden shape sorters.
  • Green Toys: Recycled-plastic toddler toys.
