your sons story sounds a lot like my sons. this is the third time i'm typing this because this place wont let me copy and paste. how frustrating! ugh anyways. my son started having breath holding spells at 6 months old also. he started having seizures after them last month in september. he's had 2 48 hour EEGS both normal. they told me that he just has "convulsions" as a result of the lack of oxygen to the brain during the spell. my daughter has epilepsy and i know that what he is doing is a seizure. they really need to learn more about what our children are going through so they can better diagnose it. i'm interested to know how your son is doing now? my son seems like he is developing normally and is getting all the milestones so far. he says mama, dada, baba, etc.
