We LOVE our amber necklace! I was skeptical at first, but was DESPERATE as our 8 mo old was waking up at least 4 times per night for several months. We gave medicine around the clock, teethers, ice, the whole deal. So I figured “what’s to lose??” Within 24 hours of putting this necklace on him, he was a different baby!! Still a bit fussy as to be expected with teething babies, but wakes up only 1 time or not at all at night, requires much less medicine and is generally more content. We are SO pleased!!
