I have been in childcare for 23 years, and when a product comes along that is exciting and creative, I feel the need to review it for other consumers. Kids of all ages love these interlocking blocks. Just right for little hands, the colors are vibrant, and the textures are new and inviting. I would recommend Bristle Blocks for all ages. One thing that is misleading is the box reads "Baby Bristle Building Blocks, however, box also reads for children 3 and up??? With any toy, children should be supervised. I feel these are a safe and an easy to clean addition to any child's toy box.
