I've been involved in child care for about four years now. It started off in high school when I took Early Childhood, and that's when I realized I absolutely adored working with children. From there, I got a position at the YMCA working in the Kid Zone interacting with children from the age of 6 months-5 years. I've had a few nannying positions working with the ages from 4-8 years. As for babysitting, I've watched children as young as 6 months up to 12 years of age.
