In the past, I occasionally worked weekdays at a home daycare as a substitute. I worked on-call, which means I work if someone calls in sick or they needed an extra assistant. My duties at the daycare included supervising children, ages 6 months to 12 years, cleaning up play areas, feeding/changing babies, lunches/snacks, occasionally taking older kids to the park, and sometimes even teaching preschool (ABC's, ABC's in ASL, numbers, and colors in English and Spanish). I have also nannied for a school age girl on nights and weekends at my house and for three families in their home.
I have also volunteered at a co-op preschool, 3 kindergarten classes, and a special education classroom for a foster group home.
