How many mom's...

How many mom's are strictly breastfeeding but also giving baby the pacifier? With my first, I bottle fed her and she used the pacifier. With my newborn, I'm breastfeeding and I'm not sure if she can use a pacifier? Sometimes she'll wake up wanting to suck on something, but I know she's not hungry. So I'm wondering if it's ok for me to give a pacifier for those times.
