These days, however, mothers have a variety of prepackaged formulas and brands to choose from.
There are three basic types of infant formula. Cows milk based formula is the most commonly sold today. Soy formulas are recommended for babies that are unable to digest the main carbohydrate found in cows milk (lactose) or who have a milk allergy. The third type of formula is specialized for infants with particular diseases or disorders. It is commonly given to premature infants and will have special preparation and feeding instructions.
