I put Cruz's on when he was 2 months old, I thought he was teething, everyone told me I was crazy, first time Mum, I wasn't sure but thought 'just in case' and put it on. He then cut his bottom 2 and top 2 teeth before 4 months old.

We only put his on him through the day, it comes off at night and we put it back on the next morning (when we remember ) I swear that thing is a miracle, I can TOTALLY notice when he hasn't had it on for a couple of days.. And now at 13 months old today he has 14 teeth and is about to cut 15 & 16, when that necklace is on teething barely bothers him, but when it's off, whoa mama!
