Helper Needed For 2 Pre-teen/teens In Upton On Weekly Basis (afterschool/evening)

I am a sole parent of two independent pre-teens/teens (close to 12 and 14 years of age) that could use some help regularly 1-2 afternoons/evenings a week while I work in Cambridge, as well with my two small dogs. The exact day(s) are flexible and can be discussed. As the children are older, responsibilities would not require constant supervision/play but are more along the lines of bringing to/from afterschool activities, helping with snack/dinner and pick-up afterwards and homework help (as needed). Of course, there is also room for fun!
