My step daughter has a difficult time. She is 11. Her mother/father feel it's not important to take her medication (Ritalin) on a regular basis. More when she feels like it. She has ADD, ODD, Tourette's, and a mental illness. I feel it would be in her best interest if she took her meds daily. Consistency to me is very important. My son was also prescribed Ritalin, it was not successful for him so he stopped taking it. Am I wrong to think this way? You take the meds or you don't?
