We had been gifted another brand teething necklace my 9 month old daughter has been wearing daily for months. We was not convinced it was working as her drooling and always fussy. I bought this brand and by the next morning after wearing it all night, the drooling was completely gone. She is feeling way better and not fussy. We are on day four or five and I'm convinced this baltic amber is truly the reason for relief and now I know with out a doubt the brand of teething necklace absolutely matters
