Introducing pacifier

If you are planning on using a pacifier, when will you introduce it? If you already introduced a pacifier, when did you? Also are you breastfeeding or formula feeding? I am breastfeeding and pumping &giving a bottle. My daughter is 2 weeks old and we are thinking about starting to use the pacifier more at 3 weeks (Especially at bedtime) because she just loves to suck! I'm not too worried abt nipple confusion because she is currently nursing and bottle feeding successfully. I'm wondering what you all are thinking!
