thank you ladies.

I'm with @babybowers, it has to be real amber. I had one and it worked wonders for us.

I really think it depends on what kind you get. It needs to be the real thing, there are a lot of cheap nock offs. But I used one for my daughter because she had really bad belly aches and acid reflux (for medical reasons) and it worked great! I noticed one day that she was really cranky and acting weird and realized later that day she wasn't wearing her necklace. So I really really have had a great experience.

I don't think it did anything, either.

Everyone will tell you something different but no, in my opinion I didn't think it worked.
