Life is a little bit easier for a blind toddler thanks to some retail workers who have been referred to as “angels on Earth.”

Two-year-old Silus Johnson from Fort Worth, Texas, is living with Norris Disease, which is a rare genetic disorder that delays muscle development and, in the case of male infants like Silus, leads to blindness. Silus has already grown too big for traditional walkers, and like most young children who require prosthetics or other aids to get around, he needed something that could grow with him.

It was Silus’s great-grandfather who initially made contact with the Home Depot employees that would change his grandson’s life. He was looking for tools to build his own adjustable walker and spoke to his local Home Depot’s store supervisor Matt Spencer, who introduced him to two employees, Eric Bindel and Christopher Wright.

Bindel and Wright volunteered to take charge of the project, and three days later, Jessica Johnson, Silus’ mother, and he showed up to check out their work. Lime green and decorated with bits of reflective tape, Silus’s walker was an immediate hit.

“As soon as we put him in there, he was spilling around,” she told CBS News. “He was able to move; the cause and effect of him doing that – that’s awesome.”

The walker is adjustable, meaning Silus will be able to use it to strengthen his leg muscles as he grows, something doctors have told Johnson is vital to his development. “We’ve already added bells on it and other toys to kind of play with; it’s really exciting to actually see him enjoy it and sit in it,” she told CBS.
