The concept of weaning: definitions and their implications

Area of Science:

• Pediatrics
• Nutrition Science
• Public Health

Background:

• The term "weaning" lacks a consistent definition in scientific literature.
• Current definitions encompass a range of infant feeding practices, from "educational diets" to cessation of breastfeeding.
• This ambiguity can hinder clear communication and research in child nutrition.

Purpose of the Study:

• To analyze the varied definitions of "weaning" used in scientific contexts.
• To highlight the importance of precise terminology in young child feeding research and policy.
• To differentiate between complementary feeding and replacement feeding for infants.

Main Methods:

• A critical review of the literature on infant feeding terminology.
• Analysis of the different processes encompassed by the term "weaning".
• Theoretical illustration comparing infant nutritional needs with breast milk provision.

Main Results:

• "Weaning" is inconsistently applied, referring to complementary feeding, replacement feeding, or breastfeeding cessation.
• A graph illustrates the theoretical nutritional contributions of breast milk versus infant needs.
• Failure to distinguish between complementation and replacement complicates research and policy.

Conclusions:

• Clearer, standardized definitions of infant feeding terms are essential.
• Differentiating between complementary and replacement feeding is critical for advancing young child feeding research and programs.
• Precise terminology supports the development of effective infant nutrition policies.
