I took comfy clothes..snacks if they let you have them.
Hygeine products. Depending what they let you have.
Something to do on the weekends like word search or something like that.
I was allowed to have my own blanket and pillow.
Some money and phone cards.
Anything you think you cant live without or to make your stay comforatble,.
Check and see what they allow you to bring.
Alot of places dont let you have products that contain alcohol. One place I was at wouldnt let me have Q tips or body powder because they said it triggers some people.
