Background: Tandem breastfeeding is defined as a situation in which a mother continues breastfeeding her child through a subsequent pregnancy, including after the new baby is born. In some countries where motherhood may be delayed and the time between births may be reduced, support for the promotion of tandem breastfeeding is necessary to help mothers continue to breastfeed their eldest child and avoid early weaning. There is no existing research about mothers' motivations to breastfeed in tandem.
Research aim: To explore the motivations of women to initiate and maintain tandem breastfeeding, based on their lived experience, framed within the self-determination theory.
Methods: A prospective, cross-sectional, interpretive, phenomenological study was carried out through in-depth interviews with 15 mothers in Madrid, who had practiced tandem breastfeeding for more than 6 months, and whose weaning of their eldest child had occurred within the previous year. Convenience and snowball sampling were used. The data were analyzed using an established interpretive phenomenological analysis process.
Results: Among the motivations for initiating tandem breastfeeding, the following themes were identified: "avoid wasting the effort invested," "desire such life experience," and "exercise the freedom to decide." The motivations for maintaining tandem breastfeeding were classified as "pass on parenting values" and "benefits of teamwork."
Conclusion: The participants based their motivation to tandem breastfeed to follow their freely chosen motherhood model. They discovered the advantages of its implementation, forming a team of themselves and their children, and healing their traumatic perinatal experiences.
