All mothers at some point during their pregnancy have to decide whether they should breast, or formula feed their infant. Background variables that have been identified which influence this decision are based on marital status, educational attainment, and age. This quantitative study investigated the main influences that this decision was based on and compared the generational differences that inform these choices. Four main themes that influenced a mother’s decision were identified, the benefits of breast milk, the ability of others to bond, maternal influence, and discussions with health professionals. Analysis of the data indicated three main themes: lack of health professional support, paternal bonding, and maternal influence. Mothers differed in their choice, depending on their experience and the support they received. In line with Government breastfeeding statistics, the uptake of breastfeeding was initially the majority’s choice, and by six weeks postpartum this had changed to mixed methods or formula.
