When you look at the studies about pacifiers -- the one in the Lancet & rewritten for Pediatrics -- um, I think early 1995, but don't remember the exact reference, the study showed that babies who used pacifiers, on the whole, bf a shorter period of time than babies who didn't use pacifiers -- the question being, was pacifier use a marker for other problems r/t bf, or was it the problem in and of itself. (That was sort of the gist of it). My concern with pacifiers is not the occasional use -- driving down the Eisenhower expressway at rush hour with a screaming baby -- perhaps a pacifier might be appropriate at that time -- but with the fact that parents get addicted to it, and cause same addiction in babies. You've all seen the cute little strings that clip the paci's to babies clothes so it can't be lost. And how many times have we seen a perfectly content baby have a paci shoved in his mouth because it has fallen out? It is used inappropriately, and in place of loving & cuddling and especially in place of bf because it isn't "time" to bf yet. In the early days, if sucking needs are taken up by the paci, many moms miss the subtle feeding cues and don't put the baby to br because he is "happily" sucking on said paci. Thus, what might start out to be reasonable use in a baby quickly turns into addictive use to PREVENT the baby from crying, rather than putting the baby to br when it is needed, or to soothe baby when it isn't reasonable to put baby to br (mom indisposed for the next 10 minutes) or on the Eisenhower. Parents panic when paci is not available, or when baby will only take ONE type of paci and it's lost or grotty. That's what makes the R--s Vanilla scented pacis so dangerous -- they are addictive and the only place one can get them is through the laboratory in Columbus, OH ($10 for 5 of 'em). So, I don't think it is the shape of the paci - I don't think it makes a bean of difference for the most part. I think it is the whole issue of the use of pacifiers in and of itself.
