It is not normal for a 2-month-old baby to cough several times a day. Normally, a child is not supposed to cough, not to mention the fact that the baby is so small, only 2 months old, and he can’t express it. When you find this symptom, you have to look for its cause, but whenever you cough, there must be a reason, either infectious, allergic or gastroesophageal reflux irritation, also possible. The more common causes: the first, a cold. Is it infected by adults or family members who have a cold in the family, or if the baby has a cold to dry sweat. The second, allergies. Some children’s fathers, mothers, and siblings have allergies and allergic rhinitis, which means that the child is prone to allergic cough. The third, gastroesophageal reflux. Because the esophageal sphincter of children is not well developed, it is relatively loose, so soon after eating milk, the milk is prone to reflux, which is what we call “milk rippling”. When the milk does not come out, but when it reaches the throat, it will be like choking on water, choking the child to cough a few times, but the milk may not come out. If the milk is so bad that the baby spits it out directly. But there are many babies who may not have a lot of milk, just gastroesophageal reflux into the throat, the throat irritation of the child coughing twice, but also no fever, nor wheezing and so on, the most common is these three cases. When a 2-month-old baby has this kind of cough, it is recommended that the family must not observe it at home, and must not just take medicine at the clinic. Try to take the child to a local regular hospital, as far as possible a pediatric department of a regular hospital above the second level, and find a doctor who specializes in listening and looking at the heart and lungs, looking at the throat, and asking for a detailed medical history so that he can determine which kind of condition it really is. If it is infectious, anti-infective treatment should be given; if it is allergic, anti-allergic treatment can also be given. However, if it is caused by gastroesophageal reflux, because the 2-month-old baby is not yet well developed, you can leave it untreated and observe it again if the overflow is not too strong. Of course, if the milk is very strong, even if it is gastroesophageal reflux, it has to be treated. The fourth one is pyloric stenosis. This is rare, is a congenital abnormality of the digestive tract, the pylorus is not well developed, too narrow, resulting in increased gastric pressure, reflux, usually jet vomiting, and very strong, this condition is generally not considered.
