Developped in collaboration with psychomotor therapists, this grow-with-me sound shapes set is ideal for stimulating and amusing baby from birth. The 4 shapes are all different to teach baby about volumes, and come in a variety of materials and colours to develop baby's sense of sight and touch. Some shapes have bells to introduce baby to different sounds. The product is evolutionary thanks to the stacking function that baby will discover as he grows, helping him to develop his fine prehension. He'll have lots of opportunities to stack them and develop his creativity. Machine wash at 30°.
