Infant formula, also known as infant milk, is a dairy product specifically formulated to replace or supplement breast milk when breastfeeding is not possible, insufficient, or not desired. Its composition is strictly regulated by European standards to meet the nutritional needs of infants.
It provides proteins, fats, carbohydrates, vitamins, minerals, and trace elements in proportions appropriate for the infant’s age. According to the WHO and the French Society of Pediatrics, exclusive breastfeeding is still recommended until 6 months of age whenever possible. If breastfeeding is not possible, or as a supplement to it, infant formula is the recommended food for infants up to at least 1 year of age, followed by follow-on formula up to 3 years of age.

Infant formula is categorized by age and specific needs:
For organic infant formula in general, specific resources are available.
The choice of infant formula depends on the baby’s age, digestive tolerance, and any specific needs. A pediatric consultation is recommended, particularly for the first prescription and in case of difficulties (spitting up, colic, suspected allergies).
Some practical guidelines: in the absence of any specific needs, a standard stage 1 infant formula is suitable for most infants. Most formulas now routinely contain DHA (omega-3), ARA, and prebiotics (oligosaccharides). Avoid repeatedly switching formulas without medical advice: this can disrupt the infant’s digestive tolerance. Any sign of persistent intolerance warrants a pediatrician’s advice before changing formulas.
Preparation requires strict hygiene to prevent infections:
Preparing each bottle just before feeding remains the rule to minimize bacterial risks. Specific resources are available for infant colic and spitting up in general.
The prepared bottle should ideally be consumed within one hour of preparation at room temperature. Beyond that, the risk of bacterial growth becomes significant, and safety can no longer be guaranteed. A bottle that is refused or not finished must be discarded and not saved for the next feeding.
Preparing formula in advance is not recommended. If necessary (for outings or childcare), the bottle can be stored in the refrigerator at less than 4 °C for up to 24 hours, under strict hygienic conditions. Reheat the formula in a double boiler or bottle warmer—never in the microwave (uneven heating, risk of burns, and destruction of certain nutrients). The bottle should be reheated only once.
Good tolerance is indicated by several positive signs: steady weight gain according to growth charts, stools that are uniform in appearance and occur at a frequency appropriate for the baby’s age, a calm baby after feedings, restful sleep, alertness when awake, and no skin rashes or significant digestive issues.
Certain warning signs warrant a pediatric consultation:
A severe allergic reaction (facial swelling, difficulty breathing, discomfort, generalized hives) requires an immediate call to 15 or 112: these signs may indicate anaphylaxis, which requires urgent medical attention. Cow’s milk protein allergy (CMPA) must be distinguished from simple intolerance and requires an accurate pediatric diagnosis before any change in formula.
Mixed feeding (alternating between breast milk and infant formula) is compatible with healthy growth: the gradual introduction of bottle-feeding helps maintain lactation and facilitates the transition. Your pharmacist remains a valuable resource to assist with the selection and use of infant formula, in addition to regular pediatric follow-up. Specific resources are available regarding the introduction of solid foods and infant care in general.
