We now recommend that pacifiers not be introduced in a breastfeeding baby until four to six weeks of age because you want to establish a good latch with the breast.
That being said, I have plenty of patients who feed off the breast very, very well and take a pacifier at night or for for naps, and they do fine with it.
Bottle fed babies it's easier to introduce a pacifier because they're already sucking from,you know, a silicone or some kind of a nipple, artificial nipple not a mom's nipple.
