To describe the experiences and expectations of Spanish women regarding breastfeeding and the support they receive from healthcare professionals, family, and friends during the breastfeeding journey, A qualitative study using an empirical-phenomenological approach was conducted. Primiparous women that had already given birth were interviewed using a purposive and snowball sampling. In-depth interviews were conducted between 1 January and 30 April 2020. The interviews were transcribed verbatim and analysed using Haase’s adaptation of Colaizzi’s phenomenological method. We recruited 14 women who had recently become mothers. Three major themes describing experiences of infant feeding by maternal lactation were identified—institutional influences, establishing breastfeeding, and cessation of breastfeeding—as well as the following 10 categories: hospital routines, lactation concerns (amount and infant nutrition), antenatal breastfeeding decision, embarrassment to breastfeed, and normalisation of breastfeeding. Prior education and support were identified as key elements in possible breastfeeding support strategies.
