RESUMEN
Pacifiers are widely used in developed societies. They are used for soothing infants, reducing their stress and pain during procedures and to help them sleep. The use of pacifiers has been associated, however, with a shorter duration and exclusivity of breastfeeding, with higher rates of otitis media and dental problems, as well as a higher risk of accidents during infancy. Recent studies have also described a relationship between pacifier use and SIDS, especially when used during infantÌs sleep. Other described benefits are analgesia and stimulation of non-nutritive sucking in preterm and term infants. There is, at present, wide debate and controversy on whether or not to recommend its use; thus it seems important for professionals and parents to be aware of the risks and benefits associated to its use, particularly related to breastfeeding. Due to the existing controversy of scientific findings, the Committee on Breastfeeding of the Spanish Paediatrics Society, publishes this review, trying to summarise present evidence with the objective of, after analysing scientific results and recommendations, making recommendations regarding the use of the pacifier in the breastfed infant.
