How to choose the best building blocks for toddlers
Choosing the right building blocks involves considering safety, developmental stage, and your child’s interests. The best building blocks for toddlers are those they can use safely and enjoyably.
First, check the age recommendation and any safety notes. Blocks for younger toddlers should be large enough to not be a choking hazard—a general guideline is that a toy part should not fit inside a toilet paper roll tube. Look for smooth edges and non-toxic materials. For more on this, see our guide on toddler toy safety.
Next, think about what kind of play you want to encourage. Classic wooden blocks are versatile for stacking and balancing. Magnetic blocks or large interlocking bricks can help toddlers succeed in building more complex shapes easily. Sets with activity cards or character themes can guide learning. Sensory blocks offer a different tactile experience. Consider how many pieces you want to manage and whether the set includes storage. For more tips on selecting toddler products, read our guide on choosing toys and storage.
Finally, the best building blocks for toddlers are the ones they’ll actually play with. Observe what captures your child’s attention—do they love knocking down towers, fitting pieces together, or feeling different textures? Start with a set that matches their current skill level to build confidence and joy in creating.
FAQ
What are the safest building blocks for a 1-year-old?
For a 1-year-old, look for blocks specifically recommended for that age, which are typically large (to prevent choking), have no small detachable parts, and are made from non-toxic materials. The magnetic block sets listed here are recommended for 12 months and up and feature large, sealed cubes with smooth corners. Always supervise play and regularly check toys for damage.
Are wooden or plastic blocks better for toddlers?
Both have advantages. Wooden blocks are often durable, have a classic feel, and are good for basic stacking and balancing. Plastic blocks can be lighter, easier to clean, and sometimes designed to interlock or connect with magnets, which can be easier for little hands. The “best” type depends on your toddler’s play style and your preferences for material and maintenance.
How many blocks should a toddler have?
There’s no magic number. A smaller set (like 12-30 pieces) is a great start for a young toddler, reducing overwhelm and making cleanup easier. As their skills grow, a larger set (100+ pieces) allows for more complex creations. Consider starting with a basic set and adding to it over time. All our picks are from the toddler toys category.
Can building blocks help with toddler development?
Yes. Playing with blocks can support many areas of development. Stacking and grasping blocks builds fine motor skills and hand-eye coordination. Figuring out how to balance pieces involves problem-solving and spatial reasoning. Sorting blocks by color or shape introduces early math concepts. Playing with blocks alongside others can also encourage social skills like sharing and cooperation.
