What information do you need? Are you simply wanting to know how or where to sign up for the class?
It has been a while since I was certified. I got First Aid and CPR (infant, child, adult) training when I was working at a daycare center years ago. It is ususlly a one- time class that lasts anywhere from 4-8 hours.
To enrol in a class you can contact several different places for dates, times and fees: YMCA, Red Cross, American Heart Association, area hospital, National Safety Council.
