Montessori sensory blocks are specifically designed for babies and toddlers who are just starting to explore the world around them. These wooden toys are blocks with various textures designed to develop fine motor skills. The set includes blocks made of solid alder wood with various textures and a safe coating. Each block measures 4x4 cm (1.6x1.6 inches), making them perfectly sized for little hands to hold. We have also included a linen bag for convenient storage in the set. Parents can use the bag to encourage their child to blindly retrieve one block at a time and describe their tactile sensations. You can introduce their babies to different textures by allowing them to touch and feel each block. Not only can they use their hand fingers, but also their feet. By developing their fine motor skills, children stimulate the areas of the brain responsible for speech development. They can learn to distinguish between soft and hard, rough and smooth, large and small, and even learn some colors. To ensure the longevity of this toy, it should be handled with care. An instruction manual for usage and care is included with the toy.
