This is a bit complicated as the nanny brings her own two children with her (she is a long standing acquaintance with no previous nannying experience). Therefore if I ask her to treat my DC in a certain way (we want to follow unconditional parenting principles) I worry that it will be seen as criticism of her care of her own children. It's not that I have seen her doing anything out of the ordinary, but concepts such as "the naughty step" and threats and rewards are really not things we want for our DC. I realise it must seem terribly naive not to have covered this issue before we employed her, but DC is still very little and I've only recently started thinking about/noticing parenting styles (I know that sounds really dim!).
Has anyone ever dealt with a similar situation? Alternatively, how harmful do you feel it would be for my DC to be cared for in 2 different ways when she is with the nanny rather than her parents?
