Debby Elnatan said hearing that her son had cerebral palsy was life changing for her.
"That was an incredibly difficult thing for a mother to hear, the Israeli music therapist recalled to the the Daily Mail. "I started to walk him day after day, which was a very strenuous task for both of us."
Now she hopes her struggles with her son Rotem will change the lives of other parents with children who can't walk.
Elnatan partnered with a Northern Irish manufacturer called Firefly to design the Upsee. The harness holds a disabled child upright against an adult's legs and feet, enabling both parent and child to walk without hindering the parent's or child's hands. (Video of families using the Upsee can be found at fireflyfriends.com).
ABC News recently interviewed a mom who has been putting the device to the test. Stacy Warden and her son Noah have been walking around together using the Upsee.
“He laughs and giggles, something he doesn’t do with other walking devices, which he sees as work,” Warden told ABC News. “I am amazed at what this has done for both of us.”Comment on this story
