We've sent some samples off for testing, but he said it would take a bit to come back.
My three year old has a long list of 'stuff' but we've never really been able to find a reason for any of it. Nothing is huge, it's just several quirks we work with all at once.
Mild hearing loss
Expressive language delay (it took a year, but his receptive language is on target finally- YAY!) This is probably not related to the hearing loss- but it certainly isn't helped by it either.
Sensory Processing Disorder- possibly spectrum related, but he just turned three and they don't want to make the diagnosis yet as he is making HUGE progress. Current PDD-nos.
Diabetes Insipidus (that's our most recent development)
Most days he's really quite a "normal" little guy, he does tire easily but not alarmingly so. I guess, if we find an answer, at least we have an answer- but I don't know a lot about mitochondrial disorders/diseases... I suppose I'm off to research land to learn more, I just needed somewhere to put this as I process...
