Michael has chronic nasal congestion. To be honest, we didn't prioritize it until recently. At first he had just started preschool and seemed to be sick all the time. Then it was winter and he still seemed to be sick all the time. However, this spring, we simply had to acknowledge something more was going on.
We took him to the pediatrician (paying our co-pay) and she referred us to an allergist and to an ENT. We went to the allergist (paying another, more expensive co-pay) who did skin testing. Many things showed up positive on that skin test but somehow I was still left with no clear answers. Then we went to the pediatric ENT (paying a third co-pay) who said that everything looked fairly normal. Come back in 3 months if pursuing the allergy hypothesis doesn't clear things up and he'll scope him to get a good look at his adenoids at that time.
So, following three different doctor visits, one allergy skin test, and two new medications we're left with some improvement in the nasal congestion and no concrete answers. I hate ambiguity.
A year ago I did a post on therapy techniques for helping children move from one-word to two-word utterances.
