Objectives: the objective was to identify the factors that contribute to early weaning. Methodology: this was an integrative literature review. Articles on the topic that were published in Portuguese and English during the period from 2016 to 2021, which were made available online and free of charge, were included. Results: The main weaning factors: working outside the home, beliefs and taboos about breast milk, cracked nipples, low income and low education of the mother, age of the mother, and babies who were born with health problems and needed hospitalization in NICUs. Final considerations: early weaning is socio-culturally constituted and for a woman to maintain exclusive breastfeeding, she needs support from her family, health professionals, society and also the government.Acesso AbertoAssistência de enfermagemAleitamento maternoDesmame precoceNeonatoNursing careBreastfeedingEarly weaningnewbornTrabalho de Conclusão de CursoCiências da SaúdeEnfermagem
