After school nanny

We have a 5 year old son who will be in reception next year . We need an after school nunny starting from September 2021. The school is in Belsize park and we live in South Hampstead.. Its walking distance (about 20 min) . Other than that we would like her to take him to any after school activities or playdates .The nunny must be able to read him in greek and also to teach him some basics in greek .
