yes a fab idea but i dont think its possible for one nanny let alone a teenager babysitter as one poster suggested to look after all 8
say that all 8 wanted to come and play during boring speechs, the nanny cant look after/be resonsible all 8 - regardless if the parents are next door (but cant see)
as i said i personally wouldnt do it as i have to protect myself and i have seen other nannys do what you have suggested and things have gone wrong and who gets the blame
THE NANNY
for children you dont know/complete strangers you need to protect yourself, its a sad that we have to but in this world we need to
for example my friend did a wedding creche, roughly how you are suggesting, boy fell over and put a fork through his nose and off to hospital he went, my friend got blamed as she apparently wasnt looking after the child properly even though she want meant to be sole charge and parents were in charge
family went back to agency and wanted her struck off
extreme case i know,but it only takes one incident and my/the nannys career could be over
just my views x
