How to Choose Early Learning Blocks

Choose blocks that match your childs skill level, your storage needs, and your values for safety and sustainability.

  1. Match the Skill: Pick sets that encourage the skills your child is practicing, like stacking, sorting and patterning, rather than just copying shapes.
  2. Open Ended Play: Look for pieces that combine in multiple ways, so a single set grows with your child and sparks creativity.
  3. Check Materials: Prefer solid wood with non toxic finishes and formaldehyde free glue, especially for toys that will be mouthed or heavily handled.
  4. Size and Storage: Consider how many pieces you want to keep out at once, and choose sets that fit your usual play surface and storage options.
  5. Pairing Ideas: Use simple prompts like sorting by color, building concentric circles, or counting pieces to boost language and math talk.
