on the necklaces, i'm in the same boat. i have both necklaces on D but i'm thinking i should take one off. the amber one doesn't seem to be helping with the teething. i'm afraid to take the hazelwood necklace off because i'm convinced it helped with the colic/silent reflux.
I took off the hazelwood and I'm going to give the amber a couple more days. If I don't see any difference, I'll switch them back. I really feel the hazelwood helped Finn, too.
