CNA Courses in Long Island

Hello... I am currently in nursing school, just finished all my pre-req's last year and am starting nursing classes tommorow. I would really like to get some hospital/medical experience but cant seem to find anything.
Does anyone know of any hospitals in the Long Island area that offer CNA courses? I looked on a few different hospitals websites but cant really seem to find anything
Also, would it be too stressful to work as a CNA and be in school? right now i am just babysitting so its pretty easy/low stress job part time job.

Thank you in advance for your help!!!!
