obsessive behaviors

My Busy Little B has been having a hard week.  The rigidity in his thought patterns has been getting worse and he's been fixating on things a lot lately.  Small deviations in "normal" are overwhelming.  He had to take a mental health day from school Friday because he just couldn't handle multiple things being "wrong"--he spent a lot of time rocking back and forth, pacing, doing repetitive movements/actions trying to deal with the changes in his world.  Once school is out, we have to wean him off his trileptal to get an unmedicated EEG and I am not looking forward to it AT ALL.  Starting the trileptal years ago really helped with the fixations and obsessiveness.  The increase in the behaviors now is coming on after a recent growth spurt--neuro did not increase his trileptal to match the growth.  *sigh*  The next few months are going to need a lot of patience on everyone's part!
