Your little one will love this soft Montessori rattle sensory ball inside. The mix of knit, corduroy, fleece and baby plush textures will stimulate your baby's fingertips, and like many of our products, TOTO can be used through different stages of development. Beginning at 3 months, it is great to stimulate those curious fingertips. At around 5-6 months, they’ll begin grasping and practicing their very first motor skills. The shape makes it particular easy to be hold. When your children grow, they can throw, toss and kick and a good ball toy just never goes out of fashion. Approx 4"
