I asked about this last week, as Mumsnet now have a Jobs section, which in theory meant that parents looking for childcarers would need to post there.
Site Stuff: Job Ads Query
Carrie said:
"The Jobs board is for companies to advertise jobs to Mumsnetters.
Small business ads are for folks running a small business to advertise their wares.
There are now classified ads for buying and selling stuff on all the Local sites, so that's the place to go if you're trying to get rid of a sofa, or buy a piano, offer local services etc.
As for nannies, childminders etc. The Nanny/cm/au pair topic is still available for folks to look for a nanny/cm or offer their nanny/cm services as well as to discuss nanny/cm/au pair stuff. If you are looking for childcare or offering childcare services, your nearest Local site might be a better bet as folks are usually looking in a specific area.
At the moment this nannies, cm , au pair section of regular Talk seems to be being used pretty sensibly for Mumsnetters to offer services and recruit. If we felt an agency was taking advantage of the site to recruit/ advertise, we'd certainly intervene."
So, yes you can... but don't go overboard and post lots of times
