My baby is a little over a week old and has developed a phlegmy cough and now it seems like he is panting when he breathes. He doesn’t have a fever or runny noses. I don’t wanna panic but I’m really worried about RSV. Has anyone else experienced this? I had my husband buy a humidifier for our bedroom but I’m not sure what else I can do. I plan to call the pediatrician first thing in the morning.
