I can’t believe this needs to be said, but…
– Withholding medication from a disabled person is not a joke, it’s not a punishment, it’s abuse.
– Withholding mobility equipment from a disabled person is not a joke, it’s not a punishment, it’s abuse.
– Withholding stim toys, comfort items or similar from a disabled person is not a joke, it’s not a punishment, it’s abuse.
– Stopping a disabled person from using harmless routines or coping mechanism is not a joke, it’s not a punishment, it’s abuse.
Stop.
Same goes for communication devices.
Sorry, absolutely right. And for refusing to let someone communicate using sign language.
