The present disclosure relates generally to a composition for feeding an infant. More particularly, the disclosure relates to a nutritional composition for feeding an infant comprising a stem-cell deficient first component and a second component comprising breast milk stem cells (BSCs). The second component is added to the first component, and the BSCs partially or fully replenish the stem-cell deficient first component with respect to BSCs. In some embodiments the first component is stem-cell deficient human breast milk and the second component comprises BSCs from the infants mothers own milk. The compositions of the present disclosure have been developed primarily as a personalized, nutritional composition providing the beneficial effects of an infants mothers own BSCs to the infant while not being able to receive the full benefits of being breastfed directly.The present disclosure also relates to a composition for feeding an infant and to processes of their production. In particular, the disclosure relates to a composition for feeding an infant comprising a first and a second component, wherein the first component provides the majority of the nutritional value to said composition, and wherein the second component comprises at least one live bacterium from human breast milk or the lactating human mammary gland. The disclosure has been developed primarily as a composition for feeding a mothers own infant, wherein the composition comprises processed human breast milk with a substantially reduced live bacterial cell count as compared to unprocessed breast milk but which at least one live bacterium, from the mothers own breast milk, is added such as to partially or fully replenish the processed human breast milk with respect to the at least one live bacterium. More particular, the composition is a personalised composition for feeding the mothers own preterm infant.The present invention also related to the combination of BSC and bacterial replenishment as described her
