Much has been written about the popular belief that early bottle-feeding of breastfed infants will result in "nipple confusion." Stories abound of babies who were exposed to bottle-feeding before breastfeeding was well established and who then displayed a preference for bottle-feeding over breastfeeding. A typical scenario goes something like this: An infant nurses well right after delivery, then stays in the nursery at night where she is fed by bottle one or more times. The next morning the baby fusses and frets at the breast, acts like she doesn't know what to do, and will not latch on to nurse. However, when offered a bottle, the baby takes it eagerly.
Having heard these stories, some parents become convinced that even a single bottle feeding during the early weeks of life will seriously jeopardize their breastfeeding attempts. Such parents may be hesitant to provide supplemental milk to their babies even when a valid medical reason exists because they fear that nipple confusion inevitably will result. However, the notion that a single bottle is likely to cause subsequent difficulty with breastfeeding never has been proved. Many breastfed infants receive one or more supplemental feedings by bottle during the first week of life, and yet go on to breastfeed exclusively. Other infants, including some whose mothers work outside the home, accept a bottle readily when the mother is absent and resume breastfeeding without apparent difficulty when the mother returns.
My own conclusion is that nipple confusion does occur in some, but certainly not all, babies. I think newborns are more susceptible than older babies to the negative effects of bottle-feeding because they are just learning to breastfeed and the volume of colostrum they obtain is relatively low. If a new baby who doesn't yet breastfeed well is allowed to take a bottle, he may perceive the longer and more rigid artificial nipple that yields a higher volume of fast-flowing milk to be easier and more rewarding than attempts at the breast. I also believe, however, that it is possible to predict which babies are more susceptible to nipple confusion. Anything that interferes with correct attachment to the breast or the free flow of milk from the breast is likely to make a baby prefer bottle-feeding to breastfeeding. Thus, the baby who is having difficulty attaching due to his mother's flat nipples and who obtains little milk due to her low supply will be more vulnerable to nipple confusion if allowed to bottle-feed than another infant who has nursed well numerous times and whose mother has protuberant nipples, with a generous, free-flowing milk supply. The important thing to remember is that even when bottle-feeds have caused a baby to nurse less well, all is not lost. By adhering to the basics of proper breastfeeding technique, using a pump to assure your own supply of milk remains abundant (see pages 124-125), and obtaining help from a breastfeeding specialist, you still can expect your baby to learn to nurse correctly and to breastfeed exclusively.
Options for Providing Necessary Supplemental Milk to Breastfed Babies
By far, the most common method for giving a breastfed baby supplemental milk is to use a bottle and nipple. Most parents and many health professionals are unaware that other options exist for feeding milk to a baby. If supplemental milk is necessary and you want to avoid bottle-feeding, ask your baby's nurse if one of these alternative methods is available in your hospital.
