Poor baby!! I knew I was never a vertical blind fan. And now I know why - they're mean and scare the babies!
My Reggie has occasional seizures. He also has unrelated severe storm phobias/terrors. There have been a few times where during one of his storm terrors, he has gone into what I would describe (non-medically) as a sort of modified/mini/non-threatening seizure. He gets sort of glazy, very stiff, and shakes, not only uncontrollably, but extremely HARD. He's fine afterward.
I'm sure (and hoping) that he'll be fine. But please don't let those mean ol' blinds get him again!!
