I'm just wondering how long it took for the necklace to work. Emma's arrived yesterday and she's had it on since then. Within 10 minutes, the red patch on her cheek disappeared and although she is still slurping and gnawing on her hand, she's not crying out in pain and isn't at all grumpy. I'm a skeptical optimist- hoping that it actually works but won't be at all surprised if it doesn't (in which case, she'll still look cute with her necklace!) so I'm just wondering what other people's experiences have been with them. Thanks!
