Our nanny has just told me that she is pregnant. She wants to come back to work after maternity leave of around 6 months. This is not my preference as I think it will cause too much disruption for my girls. They are still very young and just as they have got used to a new person they will have to cope with another change. I know that there is nothing I can do legally to prevent her returning to work but I was thinking of talking to her and trying to show her that her choices are not in the girls' best interests. Has anyone else dealt with this issue before? Any advice? Thanks
