My boy wasn't diagnosed with viral induced asthma until 6. Looking back before all that, the signs were there, but they were totally missed. He had croup at 6, 12, 18, and 24 months. Then bronchitis at 3 and 4. And many, many, colds where his cough would linger for weeks, if not months, in between. Since being diagnosed with viral induced asthma, he's been on a low "maintenance" does of an inhaled steroid, and has been a million times better. It was super hard to get him diagnosed though, and took two brutal asthma attacks for it to happen.
