Food allergies to preservatives and dyes in foods can do this and is one possibility. Get your daughter on an all raw, natural diet. Take away anything that is not a pure low sugar, low bad fat (keep good fats). Make sure her drink of choice is waters and limit the milk do to sugar contents and lactose related mood swings etc. Then be strict in teaching her right from wrong and limit tv to reinforce a positive atmosphere while she is adjusting to new diet. Also you should ask her if anyone she is around is doing the things she is copying or if they have been done to her. She may not tell you right off but keep asking. Do not mention names let her say. you do not want to lead her to say a name but sometimes little kids who are abused by someone exhibit this behavior you describe.
Thank you both for your responses. I'm new on here and thought I was posting it to Mood Disorders. Bchild1108, taking away her favorite toy has helped, we will have to continue that. And your idea about those foods, we too will try taking away one at a time to see if there is any changes. As far as depressed, I don't think so. She never mentions a headache. There are times she looks really tired and seems to act up worse when she is. Maybe it is anxiety when she can't seem to sit still or be focused on anyone thing which is also when she seems to be tired or maybe after she has had sprite. Maybe sugar does have something to do with it. Thank you for all the help. We will continue researching this and post it on the Mood Disorders also.
It does not sound to me like your daughter has OCD. There is a Mood Disorders forum that you might think of posting to. Perhaps you will get more answers there.
Ok. I am Bipolar myself. I have been bipolar since i was 6 years old. From what some of these things sound like it's just a normal childs way... Like the waking baby up, smelling poop and picking things up.
But the actual causing harm to the dog or the baby until they welp or cry and then what she said to the little girl is defently something you should be worried about and then out of the blue rages.
As far as a certain food causing it. No, not really. Some foods can spark rages or manic behavior like wheat, milk, eggs or sugar. Its known as a "brain allergy".
Does she sometimes or metioned to you she gets depressed mood, anxiety, fatigued or headaches?
How about when you put her in time out, do you make her stay there or do you give in?
Try cutting out the foods mentioned above as much as possible and try a differnt way of disiplining her. Maybe take her favorite toy away for a certain time and make sure she understands what she did was wrong and could get her in BIG trouble.
I would try this first for a couple of months, if it does not work i would recommend her to start seeing a theropist, bc they defently can pull whatever is in her head out into the open to better understand why she is doing what she does.
Hope this helps a little.
