Well my son went to the psychologist yesterday and he dx'd him with also having Chronic Motor Tic Disorder, and Depression. I talked to him about the tantrums and moods and he said it could be part of the ADHD and gave me some things to try when parenting. He said if he has a tantrum or mood swing I am supposed to set a timer for 10 min and let him have his tantrum and if he stops before the 10 min turn off the timer. He said other parents have tried it and it stops the tantrums fairly soon. He also gave my son homework and that is to say okay mom if I ask him to do something like clean his room, get ready for bed, do his homework, etc. So we will see. He also thinks if we give him a medication along with his Strattera for his tics they will maybe supress a bit.
