Some kids will only learn the hard way. Talk to the other mum and she what she decides. If she agrees to take her on then let her set the ground rules. Also let DSD accept full responsibility for paying her own board. Maybe a swift kick is the only way DSD will appreciate what she had. My DD is acting the same but she has told us that at 16 she is legally able to leave home and so she is Wish these kids would learn to appreciate what they have and not what they think they should have
