The following video was captured three years ago when Calvin was six. He was on a different drug regimen than he is today, which sapped his energy. Nowadays he isn't lethargic. Instead, he's non-stop, crazy energy. And though three years have passed, his walking has improved little if any. For Calvin, it's two steps forward one step back. He continues to be thrown off balance by the dizzying effects of the three anticonvulsant drugs he has to take. I wonder if he'll ever be able to walk safely by himself. That remains doubtful, unless he grows out of the epilepsy or unless we find a cure.
