This paper explores the role of milk-based formulae in achieving four
aspects of nutritional health in infants and toddlers: in the suckling
, to mimic the amino acid metabolism and the faecal flora of a breast-
fed baby; in the weanling, to achieve adequate protein intakes in late
r infancy and beyond and to achieve satisfactory haemoglobin concentra
tions in the early toddler years. Milk-based formulae have two roles i
n infant nutrition: as so-called breast milk substitutes and as a safe
ty net during the weaning period; the latter role may be the more impo
rtant.
