Wrap around care Nanny for one child, 5 years old, Wandsworth

We are a Greek family that would like help with after school childcare after school (primarily) for my son 5.
Also have a you ger daughter that may need sometimes to be picked up from nursery.

Willing to discuss hours if more are needed, by adding some home help, and occasional evenings and, school holidays.

Greek speaking nanny is preferred but open to all.

Thank you
