Nanny Needed For My Children

I am looking for someone to watch my boys. 2: 40-5:15pm, after school. The children will be on a schedule of snack, downtime (reading, music, art), homework, and play. The kids do best on a schedule and will need monitoring when they are in the yard playing. Some days, I might need help warming up prepared dinners before I bring the kids to their activities. Preference for someone who has worked with children professionally.
