So my 2 year old son woke up from a nap yesterday wheezing and was pretty hysterical. His chest was hurting so he was crying and couldn’t hardly breathe. I calmed him down after steaming up the bathroom and rubbing Vick’s on his chest. This happened again last night the same way. He seems perfectly fine but you can hear how hard he’s breathing and the congestion in his chest. My husband had a bad virus this week that he went to the doctor for but some pretty much gotten over it. I’m just not sure what my son could have or what else I can do to help comfort him? When I ask if it hurts he says it does. Any advice mommas?
