This is not an ordinary teether! Marcus & Marcus' fun, durable and lightweight Sensory Teether that features up to 5 different textured surfaces for your little one to explore. With bumps, ridges, dips and more, this teether is designed to simulate the different textures of food to develop a child's food-related sensory experience. This teether is ideal for picky little eaters as the textures will slowly train them to be more comfortable with various textures in food.
