They're strong enough to withstand chewing but large enough not to be a choking hazard, making them safe for your curious baby to touch, chew & gnaw on. Conveniently these toys are dishwasher safe, allowing quick & easy cleaning & sterilization using steaming, boiling, or ultraviolet light. All toys are individually wrapped in clear bags & come in a large storage container. | 【Various Shapes and Sizes】At 3 months of age, babies use their hands to explore and engage with their surroundings. Our rattles are designed with multiple easy-grip handles, lovely shapes, and a perfect size for little hands to grab and shake. They're so captivating that babies hold on tightly, promoting their grasp reflex and fine motor skill development. As babies grow, they learn to shake the rattles intentionally, further enhancing their cognitive and sensory development. | 【Several Sounds and Colors】This 10-piece rattle set provides a diverse range of sounds that help babies develop auditory awareness. As babies learn to associate the sound of a rattle with movement, they'll begin to turn their heads toward the noise. The set also allows babies to produce fun sounds as they shake the toys, encouraging their hand-eye coordination and visual tracking skills. Additionally, each rattle features bright colors with high contrast that promote vision development. | 【Great Variety of Textures】Infants typically start teething at around 6 months of age, and having teethers on hand is a lifesaver. Our baby toys feature a variety of intriguing patterns, such as animal shapes, keys, flowers, and musical instruments, all with textured surfaces. By exploring these toys with their hands, tongue, and mouth, babies can safely soothe their gums and engage their senses, providing relief during the teething process. | 【Worry-Free Customer Care】Looking for a baby shower gift or newborn gift idea?
