I am the queen of paperwork, self declared of course! When someone chooses to place their child in my care, they receive: my handbook/ contract (outlines all my policies and expectations, holidays, fees and late fees, and so on), a medication release form, photo/ transport release form, emergency contact info form, "Getting to Know Your Child" (they can outline likes/ dislikes, nap routines, other relevant info). First time daycare parents also get a "How to Prepare Your Child For Daycare" info sheet.
I don't give this out until I have a firm commitment from parents, and they must bring it all back with a cheque before I will begin care.
