Most children with recurrent colds are in poor health and have low immune function. The following measures can be taken to improve your child’s resistance. Breastfeeding as much as possible: Let your baby eat breast milk for at least three months. Breast milk is the most ideal food for children, especially colostrum at the beginning of delivery, which is rich in antibodies and trace elements and helps prevent respiratory tract infections and gastrointestinal tract infections, and breastfeeding should be encouraged. Timely vaccination: Timely vaccination against measles, whooping cough, rubella, etc. can improve your child’s resistance to these respiratory infections. Reduce exposure to pathogens: During the winter and spring seasons when respiratory diseases are most prevalent, pay attention to increasing and decreasing clothing, and try not to take your child to crowded public places to reduce exposure to pathogenic bacteria. If someone in the family has a cold, avoid contact and pay attention to ventilation at home. Increase nutrition: Eat more foods rich in high-quality protein and vitamins.
