Hold off on a pacifier

Some babies are happiest when they're sucking on something. Enter pacifiers — but there's a caveat. Giving your baby a pacifier too soon might interfere with breast-feeding, since sucking on a breast is different from sucking on a pacifier.

The American Academy of Pediatrics recommends waiting to introduce a pacifier until breast-feeding is well established, usually three to four weeks after birth. Once your baby has settled into a breast-feeding routine, keep in mind that sucking on a pacifier at sleep times might reduce the risk of SIDS.
