Your post rang a bell with me as I have been contemplating looking for work of this nature. I am not
a nanny, but a freelance writer and producer, mother of two grown-ups, an experienced tutor and a very enthusiastic cook. I generally do all of my work in the mornings, and it has occurred to me that there must be parents of older children who need after school pick-ups, homework help and nutritious well-prepared meals - and maybe enough for the parents too!
I live on the northside of Clapham Common and have been in this general area for over twenty years, have a car and could walk or drive to pick up kids.
Please do let me know if you would like to have a chat.
