Buying Guide: Key Purchase Considerations
- Age appropriateness and safety: Choose toys designed for 3-year-olds with non-toxic materials, smooth edges, and sturdy construction to withstand rough handling.
- Educational value: Look for hands-on activities that promote fine motor skills, problem-solving, color and number recognition, and early engineering concepts.
