Infants and toddlers are prone to coughing when they are sick, and with that comes the problem of phlegm accumulation in the throat area, which can be removed in a number of ways. Back patting is one of the most appropriate and effective ways to promote sputum removal, especially for young children who cannot cough up sputum on their own. When patting the baby’s back, lay the baby on his side and pat him according to the direction of the baby’s lungs and bronchi, that is, from the outside to the inside, from the bottom to the top, paying attention to the empty palm. The force is slightly strong, so as not to be ineffective, and the time to pat the back is better before drinking milk, so as not to cause vomiting. The dressing of the baby with phlegm should also be paid more attention to, not to wear too much clothing because of its cold and illness, and adjust clothing according to the ambient temperature, which is not conducive to the baby’s physical activity and will also hinder the discharge of phlegm. At the same time, babies with phlegm in their throats should not eat foods that are hot and stimulating, but should be hydrated and drink more warm water, and try to keep the air in their space clean and free of dust and other irritants. Consult your doctor and take medication that can help remove phlegm as soon as possible. It is also important to identify the cause of your baby’s phlegm. Common respiratory infections, such as bronchitis and pneumonia, require treatment that is specific to the cause. Children with phlegm in the throat should be treated mainly for the cause, supplemented by back patting, drinking water, taking expectorant medication and other methods of phlegm removal, which can effectively help clear up the child’s phlegm.
