Is it reasonable to expect that the person who cares for your children should also maintain your home? The answer depends on many factors.
The first factor to consider is whether both parents work full-time. If the nanny is on her own as the caregiver, you cannot expect as much housekeeping to be done as you can when a parent is around at least part of the time. Other factors, which must be considered, are how many children are being cared for, what are their ages, and just how much time and effort is required for the housekeepingl
You can probably expect very little care for the home if there are 2 or more children who require care. If, on the other hand, most or all of the children are in school part of the day, you can expect the nanny to do some cleaning.
A logical way to determine a realistic set of expectations, would be to put yourself in the nanny`s situation and see what you could accomplish in a day when you are caring for your children. If all your energy is sapped by child-care, you should not expect the nanny to do more than you are comfortable doing.
If there is a several hour gap when children are napping or in school, perhaps some cleaning or cooking could be expected.
At the time of the interview you may tell a prospective nanny that you expect a certain amount of housekeeping. The employee may turn out to be an amazing nanny but she lets you know that anything beyond child-care is simply overwhelming and she is not prepared to do both. You must then decide if you are willing to accept that situation.
Only if your nanny has a bloc of hours with absolutely nothing to do should you expect substantial housekeeping to be accomplished. A Superwoman might do both simultaneously, but it is not realistic for you to expect that.
Assess your Situation:
It is also very important to be as clear and specific as possible at the time of the interview to let the nanny know what is most important to you and how you expect her to allocate her time.
