We are thinking of employing a nanny to look after our two girls. The eldest is about to start school, and I would like her to be able to do after school activities and have a friend round for tea occasionally - this is one of the main drawbacks, as I see it, of after school clubs. Would a nanny be able/allowed to look after my two and also a guest child for a couple of hours? I don't envisage it happening very often, maybe once every few weeks or so. If the nanny is part of a formal nanny share (which would mean she was ordinarily looking after two one year olds and a 4.5 year old), does this make a difference? I'd want her to be registered with Ofsted. I'm struggling to get a clear answer on this, and I'd really appreciate advice from anyone who's had an arrangement like this in the past!
