Food allergies in infants, particularly in those who are exclusively breastfed, are a recurring theme in consultations, with elimination diets often undertaken in cases of "internal reflux" or "colic" noticed by parents. Frequently faced with contradictory information and inadequate support, mothers are often recommended prolonged elimination diets (particularly cow's milk protein elimination diets) or, failing that, premature weaning in favor of "special allergy" formulas.

An entire ecosystem of "breast pumping coaching" (offered by non-professional lactation influencers) is developing, representing a new marketing niche in the breastfeeding field. However, as this review highlights, much of the information in circulation is not evidence-based.

The global breast pump market grew from approximately $620 million in 2011 to over $2 billion in 2024. Wearable pumps (hands-free pumps worn inside the bra) represent a fast-growing segment, estimated at close to $900 million by 2030.
