Silicone motor skills ball This flexible, sturdy ball is truly a must-have for training your little one's motor skills! It is made from 100% baby-safe food-grade silicone. With its thin edges and light weight, it is easy to grasp and also great for teething. The shape goes in all directions, keeping your child engaged. When teeth are coming through, your little one can experience quite a bit of discomfort. Biting on a silicone product relieves the pressure on the gums, thereby reducing the pain.
