The Wonder Bowl is a soft, flexible, suction bowl that was designed with an occupational therapist to curve in all the right places. The shape encourages self-feeding by offering a higher bowl-to-mouth success rate for early feeders. The shape minimizes mess, maximizes self-feeding and grows with your child from the baby years through the toddler years. The Wonder Bowl features a strong silicone suction base, and is dishwasher and microwave safe. It measures 5" in diameter, 2.5" high and has a capacity of 16 ozs. It's made of food-grade silicone that is FDA approved, CPSIA compliant, and free of BPA, PVC, and phthalates. Suitable for ages 4 months and up.
