dear pallen,
yes, you are right about the characteristic of Filipina nanny and aside from that caregiver from the Philippines is a university/college graduate as one of the requirement in Canadian embassy, so I can surely say she can speak and read English well.
Yup, everything Pallen said about Filipino nannies being hardworking, loving, trustworthy are true. I haven't heard anything about nannies from Peru though. Pallen is the live in caregiver you're hiring from Peru? You will have to decide for yourself if they are. Will you let us know? :o) Thanks.
