In our daily practice, we sometimes come across mothers who cannot (exclusively) breastfeed. This may be due to an inadequate breastfeeding start, treatment for an underlying condition in the mother with incompatible medicine, or an underlying condition in the child that is incompatible with human milk. Additionally, there are mothers who are unable to produce sufficient amounts of milk due to certain chronic conditions (e.g. PCOS, breast surgery) or insufficient glandular tissue. There are breastfeeding dyads where the child has problems and does not induce sufficient milk production in the mother. Sometimes, even after a good breastfeeding start, breastfeeding management is suboptimal, e.g. low breastfeeding frequency or excessive pacifier use, and this renders the milk production inadequate.
