Hi, I understand what you're going through, I've been there. After the RSV, did the doctor talk to you about asthma? My oldest daughter, who is now almost 6, had RSV at 3 months old (2 nights in the hospital). For the next several years, she pretty much had a cough all winter, especially at night. We were told that she has asthma as a result of having RSV. When she catches a cold (which seemed to be all the time) it triggered the cough / wheezing and she had to use the nebulizer. Luckily she is outgrowing this, and we haven't needed the nebulizer this winter! But it was rough for several years when she was a toddler. We saw a pediatric pulmonologist for it. I would suggest asking your pediatrician to listen to his lungs and see if he is wheezing (I could never really hear it myself, but I knew when she kept coughing all night it was the asthma). Good luck with your little guy!
