Quoting diiamondchula:" i warned her i was going to take toys and tv from her today and she looked at my and laughed and said ... [snip!] ... to stay at my inlaws but that was over a month ago .. i cant see something that happened so long ago affecting her now right?"
A month after the fact? Maybe, maybe not. She may just be realizing that she isn't going back to her home anymore. But I would opt for the not factor because it has been a month. Does she have a set routine at all at home or is it more of a free for all? If she is not on a routine you should try getting her on one and that may help. Even with a child who has no issues with anything they tend to do better with a routine in place.
