RSV IN INFANTS I DONT KNOW MUCH ABOUT IT PLEASE HELP!!! THIS IS MY FIRST?

Demand the breathing treatment. I was told if my son went below 99% that it would be best to start them once a day at home because he got the croup and it stayed for 3 months and he too got sick a lot once I stopped feeding him at 3 months old (I regret that now big time). He was in and out of the Dr's office so many times that they gave me a breathing machine and albuterol to use at home. My sister went through the same thing with her youngest and they just gave her the machine at home because sometimes it is necessary to have on hand. Make sure to also run the humidifier and taking him in the bathroom with it steamy is good too. Check your home for allergens including dust and/or animal dander and don't use perfume that can be a bad thing for babies like that to breath in. Watch who holds him, if they smoke don't allow them to be holding him especially while he is sick. It is 3rd handsmoke on clothes and furniture that gets to them not just smoking around them so you have to watch that too. chances are your son allergies are very active like my sons and if that be the case you will go crazy trying to eliminate the causes. For my son dust, smoke and perfume causes him to get sick everytime so I don't dust around him, he stays away from people when they smoke and I prefer they change their clothes if they want to be around him too since it sticks to that even walking by an outside smoker at walmart triggers his asthma. And I don't wear perfume.
