How to Choose Building Blocks

Pick a set that matches how you want your child to play, and one that grows with them.

  1. Set size: Look for a quantity that allows both small models and larger structures, so children can build alone or together.
  2. Shape variety: A mix of repeating shapes and a few specialty pieces helps kids explore symmetry, ramps and creative combinations.
  3. Material and finish: Solid wood and water-based, non-toxic finishes wear well and feel nice in little hands, prefer sets that avoid harsh chemicals.
  4. Skill focus: Choose blocks to support what you want to encourage, such as fine motor control, spatial reasoning or cooperative play.
  5. Storage and care: Keep blocks dry, store in a bin or bag to contain pieces, and wipe clean with a damp cloth as needed.
