Interaction with children
In this economy where everyone wants a job, asking one if they are good at interaction with children would be a waste of time as they would obviously say yes. It’s wise then to ‘spy’ on them with the kids before hiring them.
Well she doesn’t need to know algebra or how to balance equations but a person going to stay with your children all day must have some common sense, for instance, she needs to know that water and electricity are a deadly combination, so her wet hands have no business near an open socket.
Hiring anyone isn’t a wise choice as parents today are hardly ever at home. For all you know, the nanny could be a thief, kidnapper or worse, murderer!! Try to get trusted maids, probably suggested by a friend or relative.
Children are exposed to germs all the time, a nanny that could care less about hygiene will only invite diseases.
