A friend of mine ( and she is usually right about such things ) says that, at least here, in Wisconsin, it is illegal to leave one's minor children home alone, overnight. She has good and capable boys, ages 16 and 17, but still has them stay with friends if she is to be gone on an overnight trip. If something happened in her absence ( fire or some other emergency) she says that she could be charged with neglect? by leaving them alone overnight. I'm not asking for myself, as my daughters are much too young for us to even consider such a thing, but I do have other friends who have left teenage children alone while they are out of town. One of our tenants just called to let us know that she is going away on a business trip this weekend and that her 16 year daughter will be staying alone in the apartment. It was considerate of her to tell us this, as landlords this is good information to have. I will say that I certainly would not leave this particular child alone as she is on the wild side, but I'm not her parent and so it's not my place to go there. I do, however, wonder is it is even legal for this mother to leave her 16 year old alone for the weekend. Any thoughts? Or knowledge of the legality of this situation?
