Hmmm, ADHD...are they linking it to seizures in infancy, then? My son was thought to have infantile spasms at 6 months, as you know, and although the seizures stopped on their own, he was diagnosed with ADD at age 6. It DOES run in both families, but the doctors never said one of the sequela might be ADD...of course, this was 23 years ago so hopefully they know a lot more about the condition now.
Anyway, you and your family are still in my prayers - and welcome to the Church!
