6 year old with persitant cough?

i have a 6 yr old step son with a persitant cough brought on mostly when he been playing or excited. Like today he was making a joke, every one was laughing, he was so excited he made "a funny" that everyone laughed at and he was laughing so hard he coughed so hard he vomited. Most of the time though when he coughs it's usually after he's been playing hard. My husband and his ex-wife say he has a cold..always he has a cold!! I have asked them to take him to the doctor that maybe he has allergies or bronchitis or something else that is triggering this cough. I have been with my hubby for a year and i have raised 2 older children i know when a child has a cold, this never seems to me to be a cold. The cough is always deep and hard and lasts for more than 5 minutes. Sometimes after playing hard, nothing, sometimes it's pretty bad. I am at my wits end...Any advise out there?

Sounds like asthma. Especially when the coughing is triggerd by hard playing. Talk to your pediatrician. He will more than likely prescribe an Albuterol inhaler to try out, and if that works then he's got asthma. Don't worry though, childhood asthma usually disappears by the age of five.

I think that the boy suffers from allergies with a touch of seasonal asthma. Alot of the time there is not too much that can be done aside from allergy meds. But becasue yo say that activity is also a culprit it leads me to beleive there is asthma involved... he will need to see the doctor to get a treatment and maybe even a script for a seasonal asthma inhaler such as Intal.
Keep badgering your husband to take him to the doctor...vomitting from the coughing is a result of too much mucus inside his little chest and it could become quite serious if not resolved soon. See what yo ucan dig up and present the info to your husband with an innocent "do yo think this is what he may be suffering from...?"
