Robot family.

Without you knowing, a few years ago your entire family died while someone was babysitting you. A group of scientists heard about the news and decided to make exact replicas of your family as robots. The only thing is, you dont know and still think theyre human. All three of them are programmed to be sweet and kind in every way possible, and protect you at all Costs. They have to act human around you while not being able to eat, drink sleep and having to charge.
