we also can tell when we take it off. especially when they are younger. DD2 was crazy unsettled but with the necklace on she was alot calmer. like PP have mentioned, the two times that i took it off there was a noticeable difference in her ability to cope and calmness.

I have one for DD3 but she is just sooo chillaxed that I havent put it on yet (and as RCC mentioned it just looks way too big ATM).
