My son (6yrs.) has been on Focalin for maybe 4 months or so and just recently has issues with staying in the room by hisself. It doesnt matter if it daylight or dark or if u just went to the next room or to the restroom for just a second. He follows me around constantly. I cant even put him to bed by his self in the same room with my other son (8yrs) if he is already asleep. I dont know if this is typical for his age or the meds. I dont remember my other two kids ever being this way. They dont have adhd. Just my 6yr old does.
