Some time ago I also was looking for those wooden dummy chains and spent ages looking for them - am a bit fussy when it comes to safety so I don't trust just any of these chains ...
Anyway, I found this online shop, 'uniqueforkids' that has gorgeous wooden chains! I first asked several questions before buying and their customer service is really good. I was a bit worried at first because the shop's not in the US but now, whenever I need a little gift for a baby, that's what I get.
