I have a teething 4 month old. It's crap but there isn't much I can do about it other than dose him up with Calpol, use teething powder/gel and continue in my attempts to get him to use any form of teether.
However in general conversations 3 separate people so far this week have suggested buying a teething necklace, bracelet or anklet all of whom I thought to be quite intelligent. 2 of whom also don't have children but have heard from a friend of a friend that they work miracles. 
I just don't understand why they think it would help, there's no science behind it at all and honestly they just look dangerous.
So now I'm genuinely wondering am I missing some new research which isn't just anecdotal? Or am I right to wonder why is it that rationale intelligent people seem to think that bloody amber will help when everything else I've tried so far has failed?
