Being able to chew food with one's lips closed so that food stays inside the mouth (and also for good table manners - I'm not concerned with table manners in feeding therapy, just getting the child to eat well, but post-therapy it could be a goal for the parents)
To assist upper lip closure, place the upper portion of the Y-Chew just above the upper lip.
This oral motor exercise is particularly helpful when you need to establish the concept of lip closure, as it helps the individual physically feel what it's like for the lips to close.
