These u shaped toothbrushes by #redini are perfect for toddlers just learning to brush their teeth. Perfect for kids with disabilities such as autism. My 3 yr old grandson is nonverbal autistic and allows his mom enough time to brush his teeth with this toothbrush. His mouth gets clean and he gets his teeth are protected from cavities. Great product. Definitely recommend for any child begging to learn to brush their teeth or kids with disabilities!
