Hi, Welcome to the Chat Doctor. Since a lung actually transfer oxygen from atmosphere to blood and CO2 from blood back to atmosphere. For this function it has so many air sacs called alveoli, and these alveoli keep increase in number till the child is 2 yrs. If a neonate gets any problem during neonatal (first month) period, there is almost damage to actual number of alveoli, so the function of lungs get disturbed (breathlessness, increase CO2 in body and increase need of O2 etc.). All these factors stimulate inflammatory response in lung tissues so recurrent breathlessness and infection can happen later in life. As respiratory initial virus is the commonest viral infection during this age, and needs to be carefully and symptomatically treated as chances of worsening of lung function increase having history of previous lung infection or aspiration or pneumonia. Make sure he is given all recommended vaccinations on time. And follow your doctor accordingly. Chat Doctor.
