The industry has also set up milks appropriately formulated for the following period, always replacing cow's milk, which are called follow-up or follow-up milks . These milks offer the opportunity to supply, after the 4-6 months of life, in succession to the adapted milk or in place of the breast milk, a formulated milk more responsive, compared to the vaccine, to the nutritional needs of the infant. They are generally indicated with the number 2 or the term "plus" next to the commercial name (which is the same as that of infant formula). The following milks differ from the vaccine one in that it contains more linoleic acid and iron, a reduction in sodium, proteins (which are nevertheless higher than adapted milk) and vitamin supplementation.
