This is a girl with a rare chromosomal disorder called Smith-Kingsmore Syndrome causing visual impairment who is tactually exploring a Z-Vibe for sensory motor stimulation and to help build oral tone. As part of her syndrome, she has hypotonia (low muscle tone or readiness) which affects her ability to activate her muscles in her body and her mouth. Because of this she is not yet eating age-appropriate stages of food. She also seeks out proprioceptive input in and around her mouth and usually achieves this by drumming her hands/fists into her mouth. We are trying to redirect this activity into more appropriate ways of gaining this input. She appears to enjoy the Z-Vibe although she is not yet grabbing it and bringing it to her mouth herself. You can also hear her giggling one point during the video.
