Following suggestions on here I've placed an ad for a nanny in London on childcare.co.uk and nannjob. I Put it up first thing yesterday and whilst it is very early days do far nearly all those who responded don't meet the basic criteria we set out and most of those are I imagine mailing everyone who posts anything. So how long should I give it for decent applicants to come in before considering using agencies as we don't have oodles of time.
