Babies love to mind their Ps and Qs with these fun and flexible letters that support the healthy development of biting and chewing skills. Knobby Ps and Qs offer an ideal smooth surface for new gums and sprouting teeth to practice biting and chewing skills. The long arm of the P reaches back to the molar region, where true biting skills mature. Chewing on Ps and Qs allows an open mouth for breathing and sound play! Ps and Qs are made in Maine and like all Chewy Tubes brand products, are free of latex, lead, BPA, PVC and phthalates. They are easily grasped by little fingers. Adult supervision required. Each P and Q letter is approximately 3" in diameter and 1/2" thick.
