Babies start mouthing and chewing at five to six months to strengthen their mouth muscles and exercise their lips, tongue, and jaw. The Hexagonal Teether provides a safe outlet for babies to develop these skills. All surfaces can be chewed on, but the extensions may also offer input to the back molar area. Hexagonal Teether can be used as an oral motor tool to improve jaw strength and stability, assist in self-organization, and soothe sore gums.
