Perhaps you can do a second medical opinion, with a pulmologist. They are the doctors that specialize in breathing problems, such as asthma and copd. I have asthma myself, and my coughing is very worse when I am under the weather. A lot of children do develop asthma after having the flu, and I have no clue why but it is a well known medical fact. You know when the doctor has you breathe in deep? I have a natural wheeze from my asthma, and it will sound like I'm a very old man whose smoked years on end gasping for air when I'm sick. I am so bad I have to use a nebulizer every 4-6 hours at home. It is just a thought. However, I will tell you I do not show many other signs of asthma unless I am sick or I run. I won't cough much in between. Colds will aggravate asthma, and if the inhaler helps with the cough then frankly they probably have asthma. Like Sherry said, you can have testing done if you feel your wife is over caring. However, sometimes a mother does know when something is wrong and what it is. I knew my kid was autistic before he was diagnosed. Just because it doesn't show, it doesn't mean they have it. However, to be safe, you should have them seen by a pulmologist.
