Nanny Needed For My Children - Now Hiring

I have 3 children who go to school down the street from my house. 1 is in an after school program but the other 2 need to be picked up from school every Friday at 3:20 and brought home until I arrive around 5:30. It is a walkable area, only 1 block away but driving is also an option. It is only 1 time a week. There are occasionally half days where they get off at 1 and on those days , all 3 need to be picked up.
