Hmmm...I guess I'll just keep taking it off. I don't sleep with him for naps and I'm not in the bed with him at night from about 7-10pm. The necklace is supposed to break if it gets caught on something, but I wonder if it could still compromise his breathing if it gets wrapped too tight somehow. It's pretty short. He's not able to get it to his mouth. It's good to know that others think it works! It's hard for me to tell.
PapayaVagina- I bought ds's necklace from Three Sisters Toys. They don't chew on them, but the amber resting on their skin is supposed to have an analgesic (sp?) effect. I read online that it's as powerful as Tylenol. I totally thought they were for chewing on till I read more about them.
