nipple confusion

Also: nipple preference, bottle preference

A term for a breastfed baby who seems to prefer a bottle or pacifier and then struggles at the breast. Researchers still debate whether it is a real effect.

In plain words

Nipple confusion is a common term for a baby who breastfeeds less well after being given a bottle or pacifier. Parents may notice the baby pulling off, fussing, or seeming to expect the firm, fast flow of a bottle. Some researchers think the baby learns a different way of sucking. Others think the baby simply prefers the easier flow of a bottle. Studies have not settled the question. Many babies take both bottles and breasts with no change. Nipple confusion is not a diagnosis. It is a way parents describe a problem at the breast. Mothers often hear the term from family members or in online groups.

The deeper version

The concept describes a hypothesized shift in infant oral motor pattern after exposure to artificial nipples, with a change from the tongue-driven, deep latch required at the breast to a sucking pattern suited to a bottle. Howard et al. (Pediatrics 2003) randomized breastfeeding infants who needed supplements to a cup or a bottle, and reported no difference in breastfeeding between the bottle and cup groups. Other reviews have found weak or inconsistent evidence that early bottle use alters breastfeeding duration. Clinicians now distinguish timing of introduction, method of bottle feeding, and latch quality as separate questions.
