I am looking for a nanny for 3 days per week. I have tried a couple of agencies but they seem to have a tiny selection of suitable candidates who don't seem to be any different to the usual gumtree candidates. They are fine but I don't seem to get any responses from "professional" nannies: people who have trained and have genuinely chosen nannying as a career, rather than a convenience. Might this be because the post is only part-time?
