My first son outgrew his, he had pneumonia at 11 weeks, RSv
shortly after, and his RAD acted up soooo much in
between. He also went to the hospital for it once. It was bad and with the family history on my DH's side they didn't think he would outgrow it, but around 3 he did. I just had to start nebbing him for a bad cold, but it's been over a year since I last had to, he has been great. Little one is just 10 months old and has it too. Had RSV at 10 weeks the first time.
