Until last month we had a nanny/housekeeper for 6 hours a day on weekdays. She didn´t live in but was brilliant.
Now my second child will be starting full time school in September we have a new nanny/housekeeper who will work fewer hours. She doesn´t live in either and seems to be working out well with the children and around the house so far.
Both are in their mid/late forties and have older children of their own. They came highly recommended by friends of ours and with excellent references. In both cases we had a bedding in period for them to get to know the children and our household timetable. We have been very clear about what we want to be done and also anything we don´t want. I would say on the scale of easygoing to uptight we are in the middle.
We have chats regularly about whether there are any problems however both ladies are Filipina and their culture seems to be one where they would do whatever we asked and never complain. As we and the children had such a great relationship with the previous one (and so far with the new one) and wanted her to be happy we kept an eye out for any small signs that something could be upsetting her or making life difficult (e.g. household appliance being faulty, children showing a bad attitude, an awkward timetable clash between the 2 kids´ routines, etc.)
Overall we have been lucky in that both ladies show a genuine interest in and care for our children and our children have responded well to that building a relationship with an adult who isn´t a parent but who they respect and from whom they learn and who they can turn to with questions, concerns, good news, etc.
Shop around and you should get a "feeling" when the right person comes along. I know it can be frustrating when you really just want to get childcare sorted out quickly. Good luck!
