Innobaby’s star teethers aren’t just great for teething pain, they’re considered “training teethers,” which means they’re great for a bunch of different reasons. They stimulate the muscles of the lips, tongue, and cheeks to improve oral motor skills, which aids in nursing, eating solid foods, drinking from cups, and speech development. The light and easy to grip handle also improves hand-eye coordination. BPA free, Phthalate free, and PVC free. Top shelf dishwasher and freezer safe.
