Andrew, is looking for a part time nanny in Stamford hill

Samuel is starting school in September, and Mum and I both work so on Wed-Fri we have nobody to collect him from school at 3:30 until we get home between 6 and 6:30. Samuel likes to read, play outside and be creative.
We would also consider someone to do longer hours or on other days of the week if there was a minimum number of hours, or to also look after his sister Beatrice (who is 2) during the same times. Currently she is in nursery which is open until 6 but she does get tired after a long day. Thanks for any interest!
