DP watching Inspector Montalbano on TV and apparently this was mentioned so he asked me if I knew what it was. I didn't, googled and saw various versions of pendants on very long chains (to reach down to full pregnant tummy) that had a bell inside or made tinkling noises upon movement. The idea being baby heard that in the womb and when born could be soothed by hearing the same sound. So has anyone had such a necklace and did it work? Thinking of gift for pregnant friend.
