a. Formula Requirements. A formula must satisfy the infant's requirements for
water, calories, vitamins, and minerals. Commercially prepared formulas are made
according to established standards.
b. Types of Formulas.
(1) Ready-to-feed. These are liquids packaged in cans and bottles. They
are convenient and considered relatively expensive.
(2) Concentrate. These are packaged in cans and are to be diluted 1:1 with
water. This is less expensive.
(3) Powder. This must be mixed thoroughly with water and may have
difficulty dissolving. This is considered the least expensive.
c. Formula Preparation in the Home.
(1) The choice of method is determined by the type of formula used, the
safety of the home water supply, the availability of adequate refrigeration, the ability to
utilize the method, and the amount of formula needed each day.
