I've had quite a few different experiences caring for children. One past experience being I used to watch my neighbors, before their move, for about 5 hours a day. The children ranged from 2 to 4, a 2-year-old girl, and a 4-year-old boy. Also I have experience watching my own younger cousin over summers from when she was born until around age 4.
