1. As far as diet is concerned, parents must pay attention to reasonable collocation. When adding complementary food to children, give them some mushrooms, tremella and other foods. These foods can not only supplement the nutrition your baby needs, but also improve your baby's immunity. They also have a protective effect on the cardiovascular system of infants and are very suitable choices. Because the baby is young and the gastrointestinal system is underdeveloped, it is prone to symptoms such as indigestion and constipation. If you want to improve your baby's immunity, you must take care of your baby's gastrointestinal health.

2. You can add millet porridge, mung bean porridge, purple potato porridge, pumpkin porridge and corn porridge to your baby. Because these foods have high nutritional value and can improve children's immunity, parents must pay attention to this aspect. Add complementary food to your baby appropriately. Be sure to add less at the beginning, and then add it slowly from thin to thick, which can improve the child's immunity. Try to add nutritious complementary foods, pay attention to children eating complementary foods, and choose foods that can improve children's immunity.

3. The formation of the baby's immune system needs nutrients as the foundation, and insufficient nutrition will inevitably lead to low immunity and decreased immune function. Breast milk is the best food for infants under 6 months old. It contains all kinds of nutrients, immune cells and antibodies that babies need to help them avoid diseases. Therefore, exclusive breastfeeding will last for 6 months. After that, although complementary food was added, breastfeeding should be continued until the baby is at least 1 year old. If you want your baby to grow up healthily and happily, in addition to necessary exercise, you should also give your baby more food that can improve your immunity. Only in this way can the baby stay away from the disease, increase the baby's resistance, improve the baby's immune system and resist the invasion of viruses and bacteria.

Suggest diversification of food. Food is the carrier of various nutrients. Only by ingesting various foods can the baby's nutrition be comprehensive, and the baby's intake of basic nutrients such as carbohydrates, protein, fat, vitamins and minerals can be met, the baby's growth and development needs can be met, and the baby's health can be promoted. Food diversification is the first priority.
