I bf all 5 of mine and all 5 had pacifiers...that being said, I wouldnt do it now and it has more to do with that fact that we dont know what is leeching(sp?) out of the plastic or silicone into our children. There is a recent study where they took blood samples from NB's and found they had high levels of the chemical residue of plastic breakdown in their system at birth.These chemicals are an artificial estrogen( they were trying to develope an artificial estrogen when they discovered plastic) and have been linked to early puberty, cancer and infertility in both men and women.I am trying to get rid of plastic in our home (next to impossible!) for this reason.
I just think the answer is to stop making this stuff and stop giving it to our children. Kind of OT but another reason of why not to give one.
