Both silicone and latex pacifier nipples have advantages, and the choice usually comes down to baby's preference. Silicone is sturdy, doesn't retain odors, cleans up easily and is harder for baby to bite through. Silicone is not as soft on baby's mouth, though. Latex is soft in baby's mouth and baby may like the way it retains scents, but latex doesn't hold up as well to repeated cleanings and little teeth can quickly chew through it.
