The patented, proven design and shape is the perfect size and weight for little hands and mouths. The texture of the Teething Egg is similar to a baby's gums, so they love chewing and rubbing their sore and swollen gums against it gliding in all directions. Teething babies need deep proprioception on their gums to help relieve the pain. Having a consistent, soft textured surface with a firm body underneath gives little ones relief not offered by any other teethers on the market.
