I have a child with autism who loves these Nuk brushes to satisfy the need for some sensory input in his mouth
I'll start by saying that I bought this product for a use that it's not intended for. I have a child with autism who loves these Nuk brushes to satisfy the need for some sensory input in his mouth. These brushes are just not built to be chewed on constantly and if that's what you need you should check out the items sold by Ark.  That said, my son loves these to chew on, they just don't last long enough for that purpose. I know they are not meant to be chewed on, but I  would love if they made a thicker/firmer version of this product that could be used to chew for a long time.
