Good nutrition is required for the proper growth and development of children. To obtain good nutrition it is highly essential to eat a healthy balanced diet. A balanced diet is one that has all the nutrients like carbohydrates, proteins, and fats in the right proportion. Children's need for nutrition and energy is greatly higher than other age groups. It is estimated that undernourished children have less energy and so it has a negative impact on their academic performance. The nutrients needed for growth and development are protein, calcium, vitamins, omega-3 fats, iodine, and Zinc. Good hair growth symbolizes good nutrition.

Good nutrition during childhood helps the children develop immunity against infections, ensures the good development of the brain and other organs, and improves the child's cognitive functioning. Poor nutrition can lead to nutritional deficiencies which in turn leads to deficiency disorders and has a great impact on their growth and development.

Infections are more common in children than in other age groups due to the weaker and developing immune systems in children. They are in close contact with other children in the classrooms, transport, and Day Care Centres. It is due to this reason that infections are more likely to occur in children than adults. The most common infectious diseases during childhood are common cold, ear infections, conjunctivitis, gastroenteritis, and diseases of the hand, foot, and mouth. Infections are caused by a wide range of microorganisms which may be bacteria, viruses, or fungi. Skin infections are more common in children since they are exposed to a lot of microorganisms in the ground and transmission from other children through touch. Since it is the period during which they learn toilet training habits, it is easier for them to acquire urinary tract(UTI) infections. The main cause of UTI infection in children is E Coli bacteria. The treatment includes the administration of antibiotics either orally or through IV. Depending upon the type of infection, antiviral and antifungal medications are also given. It is important to diagnose the infection at the earliest and provide appropriate treatment to avoid complications. Do remember that infections can be varied and timely diagnosis and care are of utmost importance.
