Brand new here. We have an almost 5 yr old daughter that we adopted from foster care when she was 27 months. She was placed with us at 18 months. I'm working now on getting a diagnosis for her, but she is definitly ODD. I have read that this isn't considered a primary diagnosis, but I can't see what else her behavior seems to lead to. We have a pretty open adoption with her birth Mom and Dad, so I know a bit of their history as well. Mom is undiagnosed, but has many issues including what we all believe is Bi-polar. 5 yr old is sweet, well mannered, lovable and most of the time behaves well. Her issues arise when she doesn't get what she wants right away. She becomes defiant to the point of not moving. Will simply stand where she is until she is physically moved. Today, it was because she wanted to eat something while I was working on lunch. I told her lunch would be ready soon, but she just said no to that and keep rumaging through the frig. When told to stop, she became mad and wouldn't leave the kitchen. I never know what will trigger the behavior. Yesterday, telling her to wait was ok. Today, not so much. There is no reward that will motivate her. Losing items, missing out on events, or things does not motivate her either. Right now, I'm trying to find a Dr that will take her for an assessment.
