Rationale:
1. Stomach capacity of the newborn is very small, and stomach capacity increases with age.
2. Emptying time of the stomach decreases with age.
3. Saliva production diminishes with age.
4. Infants have fewer enzymatic enzymes, and therefore have a slower rate of digestion that the adult. As enzymes increase with age, rate of digestion increases.
