Our 3 month old was just diagnosed with RSV. Has anyone had successful treatment that worked? What options?

He seems to have a very bad cold. Only twice did he choke up and stop breathing for 2 seconds. Since then he has been fine. The first visit to the Pediatrician resulted in a nasal congestion result. On the second visit, he was worse and they had him tested for RSV and he came positive. We don't want to put him on all of these medications and treatments unless we have to. It seems like we arent getting all the answers we want to make a good desicion. Has anyone had a bad experiece with the respitory treatment/nebulizer and has anyone decided to let the virus run its course and what was the outcome. He is nursing and has not had a fever yet after 1 week of getting RSV. He is sleeping through the night but seems to be a bit congested in the chest. He has slowed down in nursing a bit. We are very concerned...look forward to some help. We live in Puerto Rico where it is very humid....thanks!
