Other than croup. Please don't say croup. I don't want it to be croup. But if it is croup, please remind me of other symptoms.
asthma?
pneumonia?
was going to say croup, right after i was going to tell you to go call your pediatrician and don't trust us, clown-nose. 
It's Croup. The barking cough is the only symptom. It generally clears out within a couple of days. no need to panic.
croup, there doesn't have to be any other symptoms. I had it for most of my youth.
Sorry, it sounds like croup. I know the second I hear that horrible sound, it's on to the steroids.
My 2 year old had that about 1 month ago. his only symptom was a barking cough and a little bit of a runny nose. they gave him a liquid steroid for 3 days. After the first day, no more cough. I added a link that talks about symptoms/diagnosis/treatment. my MD also suggested a could mist humidifier and push fluids. good luck!
it could be croup sorry or asthma call the doctor and take him in
Upper respiratory infection?
Croup is easy enough to treat, Bella had it recently and she has asthma, not too bad.
If the child has no other symptoms its very likely is croup. us e a humidifier or even a steamy bathroom to ease the child's breathing.
Just watch the child for a day or two and if he doesn't start to improve then see a doctor or if other symptoms occur.
bronchitis?? Could be that nasty c letter word you don't like as well!
here is some information on it!
Signs and Symptoms
Croup is characterized by a loud cough that may sound like the barking of a seal and may be accompanied by fast or difficult breathing and sometimes a grunting noise or wheezing while breathing.
At first, a child may have cold symptoms like a stuffy or runny nose for a few days and may also have fever. as the upper airway (the lining of the windpipe and the voice box) becomes progressively inflamed and swollen, the child may become hoarse, with a harsh, barking cough.
If the upper airway becomes swollen to the point where it is partially blocked off, it becomes even more difficult for a child to breathe. this happens with severe croup. with severe croup, there may be a high-pitched or squeaking noise when breathing in (this is called stridor). a child will tend to breathe very fast, and the stomach or the skin between the ribs may seem to pull in during breathing since he or she is working hard to get air in to the lungs. The child may also appear pale or bluish around the mouth from not getting enough oxygen. these are signs that a child needs immediate medical attention.
Symptoms of croup often worsen at night and when the child is upset or crying. In addition to the effects on the upper airway, the infections that cause croup can result in inflammation further down the airway, including the bronchi (breathing tubes) and the lungs.
I hate to disappoint you but it sounds like croup. The boy I watch last year had that and he had a barking cough.
it most likely is croup. I had it myself as a kid. i would get it maybe once or twice a year. But you just have to deal with it for a while it might suck really bad yes i know trust me!! but he/she will eventually grow out of it. I do not have it any more.
My son has croup right now. He's had that cough on and off for a couple of years. He's been to the ER before to get steroids because it used to scare me. now that I know more about it, I'm not as worried. (although he has no other medical conditions) HONEY really helps. The darker the better. 1tsp every 4-6 hrs. And the hot shower. my son did that this morning when he had a coughing fit and he's sounding a lot better now.
Did you read my post? my kids have the chicken pox right now. Kids getting sick stinks!!
Reactive airway~
Allergies that make the throat tighten. not necessarily asthma tho.
My 13 yr old has had the "croupy" cough on and off for years…. NOT asthmatic. he needs warm drinks, baths, vaporizor and a doctor appt. to establish any other treatment needed.
