Before birth, babies can receive antibodies through the placenta, thus gaining immunity. After birth, breast milk contains an immunoglobulin, which can resist the invasion of allergens and bacteria and enhance the baby's immunity.

Breastfeeding can not only enhance the baby's resistance, but also protect the baby's digestive system, respiratory system and ears from infection, and this protection can even last for many years after the end of breastfeeding.

2, nutritious food

What kind of food to choose depends on the stage of the baby:

(1) within 3 months after birth, breast milk is the best nutritious food (there is no way to breastfeed or formula milk is the best choice);

(2) After 6 months, it enters the complementary food stage, and breast milk (or formula milk) and complementary food are the best food;

(3) After one year old, solid food suitable for babies should be the most suitable choice.

Be sure to eat more fruits and vegetables and have a diversified diet. Don't always eat certain foods, which will easily lead to neglect of nutrition.

3. Exercise and exercise

Exercise and exercise are good ways to enhance your baby's immunity, which can not only promote the circulation of lymph in your baby's body (because there are many anti-infective cells in lymph), but also help your baby's appetite.

Therefore, no matter what age the baby is, no matter what season, we should encourage children to exercise more and enhance their physical fitness.

Step 4 get more sunshine

We all know that too much sunlight is harmful to the baby's skin, but proper natural light can ensure the baby's immune system to work normally.

It is suggested that parents can take their babies outdoors to receive some natural light every day when the weather is fine, especially newborn babies, which can effectively prevent rickets.

Step 5 get enough sleep

Poor sleep will reduce the number of T cells in the body responsible for dealing with viruses and tumors, and increase the chance of getting sick. Therefore, from the birth of the baby, record the time when he drinks milk and sleeps every day, patiently help the baby to establish the law of life, and try to ensure the daily law of the child after he is older.

6. Balanced nutrition

Delicate, not sweet or salty, three or four or five meals, seven or eight full. At the same time, carbohydrates, high protein, vitamin A, vegetables and fruits should be supplemented appropriately. Eat less sugar, because eating too much sugar will interfere with the immune function of white blood cells.

In addition, try not to eat frozen or cold food.

7. Don't be afraid of bacteria.

Mild bacterial infections, such as colds, fever and other diseases, can help your baby improve his immunity. Therefore, when the baby has a fever or a cold, the mother doesn't have to be too nervous, just do a good job of nursing.
