This was a God send for my son thatās now 2 and heās still wearing it today. I got it for him when he was 3/4 months old because he cried and drooleda lot and was beginning to teethe so I knew if he was crying a lot and irritable before teething started, it would be down right nightmarish during. Once he got his necklace, there was a total change. The amount of drool decreased instantly and we hardly noticed that he was teething except for the new little teeth popping up. Because it worked so well for him, I had to order it for my twins that I just had. They arenāt wearing theirs yet, but I have them ready. This would be a great gift for a new or expectant mom. Sheāll be happy you got it!
