Hello Dr, My baby got infected with bronchitis at age of 9. he was dehydrated and was hospitalized, Dr started antiboitic along with nebulization with medicine ventolin, clenil and aterment/atem . may be got better in a week and after 2 to 3 week nebulization process he was 100% well but as he is turn 11 he got infected again with, dr said its same sort of illness with some effect of pneumonia ( may be bronchiolitis ) this time, may be stopped taking milk , it was very difficult for us to handle, as we were worried of dehydration. then we use Salinase drop and he started taking diet. What i wanted to know, is it normal to get infected with such issues like we do with flu , cough etc? or getting infected again and again is an issue ? its not easy to find baby breathing very difficulty so i am very worried, please advice, what we can do avoid such thing later, do formula milk cause this. also dr this time started piriton syrup. THanks
