I was a student when a tried this tool for the first time. It is a great helper in therapy and oral training! For younger kids it should be a little bit smaller. In the future maybe you will produce a special version for the little ones.
For teaching the concept of tongue lateralization and/or tongue elevation|||ARK's oro-Navigator™ is an oral motor tool specifically designed to promote lateral tongue movement. Use it to navigate the tongue from side to side to establish the concept of tongue lateralization, or up and down to establish the concept of tongue elevation. Simply place the cuff over the side (or front) of the tongue to guide it.
Caution: this therapeutic tool should be used under adult supervision at all times.
