I don't really have a good answer, just my own experience. When my daughter was between 1-2, she was sick all the time, she seemed like she'd have a few good days and be back to another cold. Sick so often my dr. did test her for an auto-immune disorder and the tests came back fine. When she was a little over 2, she had a full blown asthma attack- we had no idea what was going on, we were out of state at the time, I literally almost killed her. Not a big deal now though, since we know what to look for and what to do, and she seems to be growing out of it. All the signs I thought were of a cold (coughing, sneezing, tired) were really allergies kicking in. And she would fever all the time for her molars, but I didn't separate the symptoms, I always thought she had nasty colds. Another thing I have learned with allergies and asthma, if she does catch a cold, it's a big deal. She gets much more sick than the rest of us, and it lasts twice or 3 times as long. After the asthma attacks started we had her allergy tested, and she was crazy allergic to dust mites and cats, and moderately to a list of other things. My husband and I have 0 issues, nothing in our history, I never would have thought in a million years. On the other hand, my younger son is sick quite often, not as much as she was, but still a lot. And he's fine. So anyhow, that's the next step I'd take if you feel like you need one, get her allergy tested- and if you do it, don't just do the pediatric panel, it's fairly worthless. Come up with a specific list, or ask your dr. for something more broad. You can also (I learned after the fact) do the blood test for auto-immune and do the allergy screening with the same sample. No need to do them seperately.
