The infant brain undergoes rapid enlargement in size during the first two years of life, accompanied by a period of rapid cognitive development. Metabolic acidosis can have a negative impact on developmental outcome in infants. Nutrient digestion is not fully developed at birth. Each of the different digestive enzymes produced by the exocrine pancreas appears at a distinct time in gestation and their functional capacity increases postnatally. For instance, pancreatic amylase is scarcely detectable at birth and begins to rise after the first month, continuing to increase during the first two years. Other sources of amylase (breast milk, intestinal, salivary) also confer some benefit until the infant matures and the pancreas assumes a more dominant role. In contrast, the developmental pattern of disaccharidases reveals that full term infants are able to digest lactose and other disaccharides from birth.

Lowering blood pH, which occurs with systemic acidosis, leads to physiological responses to normalize pH in the host, including stimulation of the respiratory centre to increase the respiratory rate; the kidneys also increase excretion of hydrogen ions. Compared with older children and adults, acid loading of infants results in larger falls in blood pH and total CO2, a smaller and less rapid fall in urinary pH, and much smaller increases in urinary titratable acid and ammonium. The immaturity of renal acidification accounts for the relatively large changes in blood pH resulting from minor changes in diet.
