Occasional Afternoon Babysitter Needed For 2 Children In Northampton

I am looking for occasional after school care for my two girls usually a Tuesday; average of one 3 hour shift per week. They can be walked (or driven in bad weather) home from school which lets out at 2:10 p.m. Some evenings they need to be driven to classes. Occasionally if there is no school I may ask for a full day. It is not required that someone is available for all shifts (as the day(s) of the week needed can vary from week to week - we could look at the calendar each month and see what will work. Safe driving and a car is necessary. Either English or Spanish speaking.
