I make weighted blankets and donate them to the public schools for those that are inclusion students. One of the therapists told me the blankets envelope the kids more, however, the vest may work also. I do know a set of autistic twins. One prefers the best and wears is constantly. She is very shy. The other is extremely outgoing and prefers the blanket.
Also, studies show that adults with extreme migraines do well with them also
please make sure the weight is proper for each person
