Looking for babysitter, after school, four days a week

We are a bilingual family looking for someone to take care of our 5 year old 4 days a week, from 4-8pm. Picking him up from school and giving him a bath are the only real jobs to be done, the rest of the time we would like you to play with him!
Please reply by PM if you can commit to one year.
The area is Belgrano/Nuñez
