Food is an essential life need of every living being. Its basic role is to enable the occurrence of all necessary life activities and optimal growth and development. Due to the dynamic growth and development of the infant, nutrition is a particularly important link in this period of a child's life. Since nutrition has played a very important role from the very beginning, its influence is reflected in later life. Throughout history the practice of feeding children has included; breastfeeding by the biological mother, breastfeeding by the nursing mother, and bottle and formula feeding. The basic components of an infant's diet are dairy nutrition and supplementation. Every food that a child consumes except milk is a supplement. In situations when a child consumes artificial milk in addition to breastfeeding, it is a mixed milk diet. Breast milk is the most natural form of infant nutrition and as such has an advantage over other forms of nutrition. It meets the specific needs of the child and is a prerequisite for his optimal growth and development. It has nutritional, psychosocial, practical, economic and immunological advantage and function. If the mother does not want or is not able to breastfeed, the alternative becomes a milk formula, that is, a factory milk preparation. As a child grows, his energy needs also increase. At the end of the child's sixth month, breast milk no longer meets the need for energy and protein, and then a complementary diet is a substitute. The period between the fifth and sixth month of a child's life is the optimal time for the introduction of supplementary feeding, taking into account the child's body weight. In specific situations such as celiac disease, nutritional allergies and digestive problems in children, the infant requires a customized, specific diet. One of the most common digestive problems is vomiting and constipation. This paper presents three basic types of child nutrition: milk feeding, complementary feeding and vitamin and mineral supplements.
