In a relatively new concept in teething, The First Years introduces this massaging action teether. The concept is really quite simple: offer even the youngest infants a means to massage their gums at will. The massaging action increases circulation, thereby helping to alleviate swelling and discomfort. This soft, yellow, star-shaped teether has a smiling face and three nubby points that vibrate when a child bites down on them. The star sits upon an oversized blue plastic handle that's easy for even the youngest child to grasp. There's also an opening at the bottom of the handle that accepts a toy strap. The star rattle is surface washable and is powered by a nonreplaceable battery that's sealed inside the teether's handle for maximum safety.
