A nanny focuses primarily on childcare — feeding, play, school runs, and a child's daily routine — while a maid covers general housekeeping such as cleaning, laundry, and kitchen upkeep. Some candidates combine both skill sets; check individual profiles.
The distinction matters most when you're setting expectations before day one. A family that hires a nanny expecting full house cleaning, or a maid expecting structured after-school supervision, is usually the family that ends up unhappy within the first month — not because the candidate did anything wrong, but because the role was never clearly defined. Before you interview anyone, write down what a typical day should look like: which hours are dedicated to the children, whether any housekeeping is expected, and who handles meals.
It's also worth deciding early whether you want a dedicated nanny or a nanny-housekeeper hybrid. Hybrid roles tend to suit smaller households or families with older children who need less hands-on supervision; dedicated nanny roles suit households with infants, multiple young children, or parents who work long or unpredictable hours and need someone fully focused on the kids. If you're unsure which fits, it's usually easier to start with a narrower, dedicated role and expand responsibilities later than to walk back an overly broad job description once someone's already started.
