Is there anyone out there that works full time, and I mean really quite long hours,ie;7-7x5 days a week plus some ' on call ', and has a large family ? I have 5 aged 5 and down, and we are hoping to have at least one more...my dilemma is should I employ a second nanny/au pair to ' back up ' my live in nanny or maybe add in some nursery/childminder ? Anyone else with experience ? We have space.....££ is a consideration too
