Inexpensive Nosey Cup

Has your child's speech therapist, feeding therapist, or occupation therapist encouraged you to purchase a "Nosey Cup" for your
child?  This can be an expense some families just cannot afford especially if the cup is being used on a "trial only" basis,
so why not try making your own with a simple disposable bathroom cup (wax treated are more sturdy) to practice at home.
Just cut out the right size for your child, and dispose/remake as needed.
