This is fascinating to me! DS12, who seemed very bright when younger and who has a HG+ sister and a MG(+?) brother was diagnosed with his first ear infection when he was 16 months old. But, we immediately realized that he'd been having ear infections for months. He continued to have multiple ear infections for about 6 months until, just shy of us putting in tubes, he stopped getting them. Then, after a year of not having them, he started getting them frequently. Again, after long-term antibiotics and just shy of tubes, they stopped again. And then, about a year-and-a-half later he started getting them frequently again. He was placed on long-term antibiotics and then had a severe allergic reaction to the antibiotics, but he stopped getting the ear infections. At only two points was his hearing tested, and it tested normal (although it wasn't extensive testing). So, no tubes. When he was 5.5 he had a tonsillectomy/adenoidectomy and then severely hemhorraged. After that he had two more ear infections and then they stopped. Funnily enough (not really!) no one seems to think any of this could lead to any of his learning characteristics. I guess I should look into this further.
