Infant formula is a manufactured food designed for feeding babies under 12 months of age.

It is often called baby milk, formula milk, or simply formula. This food is made to simulate human milk or serve as a complete or partial substitute for it. It is usually prepared as a liquid or a powder that must be mixed with water.

Once prepared, it is typically fed to infants using a bottle or a cup. This food provides necessary nutrition when breastfeeding is not possible or chosen.

There are several medical reasons why a baby might use formula instead of breast milk. Sometimes, a mother's health makes breastfeeding unsafe for the infant. For example, a mother with HIV has a 5% to 20% chance of transmitting the virus through breastfeeding. Other viral risks include cytomegalovirus, which can be dangerous for pre-term babies. Mothers may also have infections like herpes simplex or chickenpox. In these specific cases, using formula can help avoid passing these infections to the child.

Infants may also require formula due to their own biological needs. Some babies are born with inborn errors of metabolism, such as galactosemia. This condition makes it difficult or impossible for them to process breast milk. Additionally, some infants may be at risk for malnutrition. This might involve deficiencies in iron or vitamin D. In some places, like Canada, infant formulas are fortified with vitamin D to help prevent these issues.

Beyond medical needs, many social and personal factors influence feeding choices. Some parents choose to use bottles so that fathers can play a larger role in parenting. Financial pressures also play a role, such as when maternity leave is unpaid. Some mothers may find breastfeeding difficult due to work, school, or religious settings. Mental health is another major factor. The intense pressure to breastfeed can lead to postpartum depression or a decline in mental well-being. This pressure can even cause physical issues like milk depletion or poor latching.

Health organizations provide strict guidelines to ensure these products are safe. The World Health Organization (WHO) and UNICEF published a Global Strategy for Infant and Young Child Feeding in 2003. They stated that processed foods for young children must meet standards set by the Codex Alimentarius Commission. A 2001 WHO report also found that formula prepared to these standards is a safe substitute for breast milk.

These rules help ensure that the food is nutritious and reliable for families worldwide.

Despite these safety standards, there are documented health differences between feeding methods. Health authorities widely advocate for exclusive breastfeeding during the first six months of life. Currently, 48% of infants under six months are exclusively breastfed worldwide. In the United States, the rate was 24.9% in 2025. Studies have associated formula use with certain increased health risks. These include risks for asthma, eczema, obesity, and type 1 or 2 diabetes. Some research also suggests a link to lower cognitive development.

Choosing between breastfeeding and formula involves balancing many different risks and benefits. In developing countries, the risk of diarrhea from unclean water used to mix formula can be very high. This risk often outweighs the risks associated with breastfeeding in those environments. In other cases, families use the "AFASS" principle to make decisions. This stands for making sure the choice is Acceptable, Feasible, Affordable, Sustainable, and Safe.
