This is a video of the daily walk Oskar and Klaus take. It was recorded on January 31st, 2012. Oskar is around 9 months old in this video, and Klaus is 8 years old (if not older). Oskar is 100% blind and has been since birth due to genetic factors. He was born without developed eyes (his lids are basically fused shut).
