How ’Normal’ Is Regression?

Hi Everyone, it has been awhile for me as my DD6 has been doing pretty well.......until the last few months that is.

I am wondering how normal is regression in behaviour/ADHD symptoms?  Why after months of moving forward and no aggression and such a happy go lucky kid am I now seeing anger, outbursts, crying spells at school - back to the old way things use to be.  There is no major change in anything.  She is on Dex and has been for one year. 

Whenever she storms off or threatens to hit me or does actually hit her brother I find myself thinking......"this is not nearly as bad as it use to be, but at the same time in the back of my mind I am terrified we are headed that way again"

Is this just a normal ADHD stage of development if there is one?  The first two months of school her teacher described her as "the model student" She was surprised when I told her she has ADHD.  By the next few weeks DD is having meltdowns, not being able to calm herself down so being sent to the P. office....refusing to participate, etc.

She also keeps talking about an upset stomach and bad dreams.  The stomach upset never lasts more than 5 minutes and happens randomly.  When I ask her about the bad dreams it is just a "I don't remember, or a ghost or something random"  She never wakes up scared or afraid.

What in the world is going on ???

She may need a dosage increase.

Do you think there is more going on than just adhd? Do you believe you need a new evaluation?

What does the teacher think? I would think they would be offering ideas to help her rather than just sending her down to the principal's office.

Our son is on concerta AND guanfacine. This helps relax him. He has sensory and when he was younger, he couldn't self regulate. he would come in from recess and couldn't calm down. This helps him with all sort of things.

I would call her prescribing doctor, tell them what is going on AND call her teacher as well.
