Doctor's answer:

Raising with formula milk, cow's milk, goat's milk, soy milk, milk cakes, or other substitutes is called artificial feeding, with cow's milk being the most exclusive. For infants under 6 months, it is essential to ensure they receive a certain amount of fresh milk. However, as they grow older, it is often difficult to rely solely on fresh milk, so formula milk can be added for dilution.
The calculation method for milk intake is as follows: For example, a 5-month-old infant weighing about 6 kilograms requires 110 milliliters of milk per kilogram of body weight per day, along with 5% to 8% of sugar. The calculation is as follows:
Daily milk requirement: 110 × 6 = 660 milliliters (can be divided into 5 to 6 servings)
Daily sugar requirement: 660 × 5% = 33 grams (about 2 tablespoons)
Daily water requirement: 150 × 6 = 900 milliliters
