From birth to 5 months, milk is the essential and unique food of the newborn. The French National Nutrition Program (PNNS) recommends exclusive breastfeeding "up to 6 months and at least 4 months for a healthy benefit". However, only 36% of infants 0-6 months of age are exclusively breastfed worldwide. Some mothers choose to give infant formula to their baby in the first few months of life. This decision may be a personal choice or be imposed by pathophysiological situations. The nutritional requirements of the infant are specific, which implies adequate nutrition. Infant formulas and follow-up formulas are therefore complex products, specially developed for a group of vulnerable consumers. In fact, the compositional and information requirements for infant formula are highly regulated. This study, defined as a pilot study, proposes to evaluate the innovative "TrueGreen" BIO infant formula based on a new whey extraction method on the growth and tolerance of infants from 0 to 6 months compared to the conventional BIO infant formula. As no growth and tolerance data are currently available for this new TrueGreen BIO formula, this study aims to determine them.
