I would say they are perfect for those just starting to walk and the like. Maybe 18 months or something? They are very cute and soft despite being slippery so I didn't expect them to be able to hold a baby or be used as an obstacle course or anything. They are great as toys or for stacking blocks. Again, they're small, not as big as preschool ones, but they're cute and can be used as educational play blocks.
