What is the difference between daycare and babysitting?

DAYCARE is when an adult/adults run a business at their house or at a separate building. The children get dropped off there. There are many more children and they aren't related to each other unless the parent drops off siblings.

BABYSITTING is when a teenager/adult is asked to come over to the family's house. They watch the kids directly from their home, and there are usually no other children other than the familiy. The parents eventually come home, the babysitter gets paid, and he/she leaves.
