Pacifiers?

L

How many of you use pacifiers? I read it can cause some problems / nipple confusion.

I do not plan to EBF because I am having twins and want to tandem feed to keep them on the same schedule. So in public I plan to use bottles with breast milk (hoping for a good supply!). Mentioning b/c I think that may make a difference in whether or not pacifiers would really cause a problem.
