Amber Beads

M? • TTC baby #1!
July 9th baby over here and I'm pretty sure we're entering, or very close to entering, the dreaded teething stage!  Anyone ever use or hear good things about amber necklaces and anklets??  I know they're becoming more and more popular but I'm nervous they're just a scam.  Also, if you have used them, where did you get them from??  Thanks!
