looking for helper to care for newborn and a difficult dog

Chinese Singaporean family looking for a lovely helper to help with caring for newborn and household requirements (cleaning, cooking etc). We also have a medium size difficult stray dog who is afraid of strangers (may bite so helper must strictly follow our instructions). -Must have experience with taking care of newborns and dogs! -Must be able to speak English. Able to speak mandarin is a plus. Prefer to deal direct, no agent.
