Childcare Needed

We are looking for a reliable, friendly babysitter to occasionally pick up our 6-year-old son from school and spend a few hours with him until we get home. This would be on an as-needed basis rather than a regular daily schedule, and we would be able to provide plenty of advance notice. We're hoping to find someone who is available for occasional weekday afternoons. Responsibilities would include school pickup, transportation home, and spending time with our son.
