Parents need to take the baby to the hospital for some tests related to immune function to clarify the specific treatment plan, and can routinely apply some immune-boosting drugs for treatment, such as oral lyophilized splenamine-based powder. Younger babies can improve their resistance through acupressure and massage, while older babies can also do physical activities in their daily lives, and appropriately increase their aerobic exercise such as running and jumping, which will help strengthen their physical fitness and improve their immunity. In daily life, children should not be partial to food, not picky, to balanced intake of nutrition, and to ensure sufficient sleep every day, are conducive to the improvement of the baby’s immunity, to avoid recurrent respiratory diseases, or other system diseases caused by fever.
