Pacifiers? Yay or Nay?

Here is an interesting post about pacis: http://blacktating.blogspot.com/2009/10/you-are-not-pacifier.html What do you think? Yay or nay? Do they go with bottle feeding for additional sucking comfort? I was waiting 4-6 weeks with Claire to intro one, but by that time, she wouldn't ever take one! Sometimes I think it would have been super-nice to get a break once in a while, but it's kind of scary how huge the link is with pacis directly causing mastitis (a breast infection) in the mom because the baby sucks at the paci rather than the mom and never completely drains the breast tissue. Pacis (like nipple shields) also are linked to earlier weaning. I don't know...ultimately, like all these other things...are a very personal choice made by each family.
