Perfect length for my baby. He was teething so bad that there was always drool, crying, and constant gnawing on a toy/blanket. When the amber necklace came and I put it on him I was skeptical it wasn’t doing anything and I thought “maybe it just came right when his painful teething has subsided.” Then I took it off for bedtime, and he was so tired but he was restless and kept gnawing on his blanket with his eyes closed. He was tossing and turning so much it was keeping me up. So I put the necklace back on him And for the rest of the night he was peacefully sleeping. Life saver for my baby and me!
