We use the Avent ones. It is all DD will take. She was never one to suck her hands but was a comfort sucker on the boob. So we introduced the dummy and it was the best thing for us. We've tried other brands but she refuses them.

I remember someone saying the NUK newborn dummies were recalled (whe DD was a newborn) because babies were found with them whole in their mouths as well as not having enough "space" and so had a suffocating effect... or something like that. I'm sure they've adjusted the design by now but I've never been able to shake that from my mind so won't buy that brand.
