Breastmilk is the ideal food for infants: it is best adapted to their specific needs. A healthy and balanced diet of the mother is important for the preparation and continuation of breastfeeding. Mixed breastfeeding can interfere with breastfeeding and reduce milk production. It’s hard to reverse the choice of not breastfeeding. If an infant formula is used for a non-breastfed baby, it is important to carefully observe the instructions for preparation and use and to follow the advice of the medical profession. Incorrect use could pose a risk to the child’s health. Socio-economic implications must be considered in the use of infant formula. After 6 months, in addition to breastmilk, water is the only essential drink. Do not hesitate to consult your health care professional if you need advice on feeding your baby.
