Authentic Polish amber, hand knotted between each bead for safety.  Soothe and calm your baby with amber.  Natural succinic acid is released by body heat when worn, and is known to be a pain reliever which helps baby cope with discomfort.  
Wear as a necklace during the day and if you have safety worries, put on baby's ankle at night to keep the contact with the skin.  
These necklaces are not for chewing.
