When a nursing child develops a cough, the cause of the cough needs to be found. The mother generally needs to moderate her diet to be able to provide her child with better nutritional milk, thus reducing the symptoms of the cough and also helping the child’s growth and development: 1. External stimuli: Some children’s coughs are dry and similar to choking due to external stimuli, such as the stimulation of odors or water can cause a transient reflex cough. Mom should try to consume foods that are low in salt, sugar and relatively low in irritating odors, avoiding the intake of barbecue, pickles, fish and seafood, as well as the need to quit smoking and alcohol, which can have a relieving effect on a child’s irritating cough. 2. Disease factors: When a child coughs with apparent phlegm, it may be caused by an upper or lower respiratory tract infection, such as bronchitis or bronchopneumonia. At this time, the mother should try to consume a light diet that is easy to digest, such as gingko lotus seed porridge and radish soup, not to consume foods with too much protein or fat content and greasy foods, as well as to reduce the intake of foods that can easily catch fire, such as longan, papaya, cinnamon and oranges. This will strengthen the child’s constitution, avoid fires and help to relieve phlegm. When your child has a cough, you can continue breastfeeding and create a good living environment by keeping the air in the room clean, moist and circulating and at the right temperature. When the child coughs, the mother can pat the back to promote the discharge of irritants. In addition, mothers should always keep an eye on their children’s health. If the coughing symptoms persist and cannot be relieved, they should seek medical attention and take medication as prescribed by the doctor.
