Baby Bertie learning blocks grow with the child from infant to toddler. The soft, food-grade silicone blocks can be stacked, squeezed, and chewed, making them perfect for teething babies. Each block features raised numbers, textures, and charming sea animal illustrations to stimulate tactile and visual development. With a two-side interlocking design, the blocks are easy to connect and stack, which develops fine motor skills and hand-eye coordination. These blocks support early cognitive development in a natural, fun way.
