I have never heard of amber teething necklaces, but I saw the strangest thing at church on Sunday night. A baby, less than a year old had on a weird looking necklace. When I asked what it was, she told me it was nettle root. The baby doesn't eat it...I guess just being in that close proximity is supposed to help with the teething through osmosis. First of all, it kind of bothered me that the mom would have a string tied around the baby's neck...dangerous. I don't understand the nettle root part either. Maybe someone on here can enlighten me.
