This design challenge came from @reginask
This item is for a family’s son who seeks/needs a lot of sensory input on his face/head. He absolutely loves vibration through various hand held massagers and OT tools.
They have used hand held battery operated massagers and OT tools called a zvibe to help with sensory input
Parents would love for him to have a chain that he can wear that with a squeeze they (and eventually he) could turn on himself and lift to his face to help self regulate. The ones they have commercially require turning on in a way that his little hands can’t manage. Developmentally he’s not at a point where he can go and get something but if he can wear it, it will always be with him and eventually he can turn it on himself. He’s not a chewer so the chains that are good for chewing don’t work for him.
