This product was recommended to me by other moms for teething. Before the necklace my girl was fussy, wanting to be held all day, & chewing on her hand basically from the time she woke up till she went to sleep. After about 1 hour of wearing it this was her. She was extremely happy & active. She then took an amazing nap. I am very satisfied with the results of our amber necklace making our teething season much more bareable.
