Most of intended parents are unable to breastfeed , however commercial iron-fortified formulas can provide the nutrition that is necessary for a baby. There are different types of infant formulas:

1. Formulas based on cow’s milk – cow’s milk formulas resemble human milk so that it is easier for a baby to digest. However, some babies might be allergic to the proteins cow’s milk contains. That’s when other types of formulas come into play.
2. Soy-based formulas – In rare occasions, some babies are lactose intolerant. Besides, soy-based formulas can be useful if parents want to exclude animal protein from a baby’s diet.
3. Special formulas – special formulas are used for the babies having special dietary needs. This might include babies who are premature or deal with different disorders. Special formulas are usually prescribed by a pediatrician.
4. Hydrolyzed formulas - hydrolyzed formulas are used for babies who don't tolerate cow's milk or soy-based formulas. Extensively hydrolyzed formulas are an option for babies who are allergic.

Infant formulas come in 3 main different forms:

1. Powdered -  powdered formula is the most affordable. Each scoop of powdered formula must be mixed with water.
2. Liquid - this type of formula also must be mixed with water.
3. Ready-to-use -  ready-to-use formula is the most convenient type of infant formula. It does not need to be mixed with water. However, ready-to-use formulas are the most expensive ones.

It is always recommended to consult with your baby’s pediatrician before using any type of formula.
