Hong Kong family looking for helper

We are a family of 4, 2 adults and 2 kids (1 approaching 3 years old and 1 newborn in coming November). We are looking for a domestic helper to assist us to take care of our kids (ma’am works at home so you wont be looking after 2 kids on your own), cook meals, marketing and do household chores. You will be having your own room and off on Sundays under normal situation. Looking for a helper who is careful, detail-minded, responsible, reliable and willing to learn.
