My son had RSV at 4 weeks which gave him pneumonia, and he was in the hospital for a couple of days. They said that everyone gets it, it's just very dangerous for preemies (my son was not a preemie). He got better on his own without medication, but it took a couple of weeks. It was kind of scary because he had trouble breathing due to the congestion, and he was so young. The commercial does scare you, but don't worry, they are taking care of it. Hope he is feeling better soon!
