Proper nutrition significantly affects growth and development in childhood. It is necessary for the child's mental, emotional and social development. During this period, it especially enables the organs and the whole organism to reach their full potential. With proper nutrition, we ensure a sufficient intake of energetic, building, regulatory and protective substances. The child's brain begins to acquire information already during infancy. Water, as an important factor in the body, actively regulates various chemical reactions and maintains blood supplies, so it is necessary to accustom children to water as the main source of fluid. The amount of food that a child should consume depends on the age and gender of the child, as well as physical activity. Children who are more physically active should eat more food rich in nutritious nutrients. Breastfeeding has important advantages for the child, but also for the mother. It strengthens the emotional connection between the child and the mother. In the fourth month of a baby's life, there is a period in which he is introduced to food that is no longer exclusively breast milk. After the age of eight months, solid food predominates in the baby's diet. This transition is necessary in order to see if the infant has developed sufficiently only on solid food. During this period, it is necessary to offer him as many foods as possible that he can take in his hands and learn to feed himself. In the following period, after the child reaches the age of one, he slowly becomes independent and eating becomes a pastime for him. Children starts to play with the spoon during feeding, which is an indispensable factor in development. The meals are more varied, richer and similar to the adult menu. After the third year, children at this age have developed their motor skills well enough, and they can feed themselves without the help of others. A child is moving into a period when it is growth is relatively uniform, it is quite active and consumes large amounts of energy. It is important that all the child's meals are in small proportions. If food intake is higher than recommended, obesity may occur, especially if children are not physically active enough. It is important for parents to be aware of potential dietary difficulties such as allergies or anemia. For the better health of the child, it is necessary to maintain a strong immune system that protects against various diseases. Regular inclusion of vitamins and minerals in the daily diet helps to strengthen immunity.
