My son was diagnosis with ODD when he was a young 5 year old. He began sweet as pie and something snapped. At 3 and 4 we were laughing and saying the terrible twos came late. At 5 we were wondering when they were going to leave. We took him to a psychologist who did play therapy. After about 6 sessions she said ODD. My husband and I, I guess, were in denial and felt that Bo would change over time. He is 9 now and worse than ever. I worry about medication treatment. Under it all he is creative, great at football and energetic. These I dont want to alter with medications. Can someone please tell me what the effects of these medications are and if you have tried several then let me know what has been the best.
